Berlin, New Hampshire

Berlin is a town in the Great North region of New Hampshire. Berlin is a great destination for those who want to enjoy the outdoors. Outdoor activities available in this town of 9,400 (2020) residents include fishing and paddling on the Androscoggin River and miles of ATV trails in popular Jericho Mountain State Park.

Located on the edge of New Hampshire's northernmost White Mountains, the town was once known as "The Town in the Trees." Berlin, New Hampshire grew as a city on the backs of the logging, paper, and pulp industries, and at one time was the center of these industries in the United States.

At one time Berlin's mills hummed, logging timber was washed off the Great North Woods, and logs clogged the Androscoggin River, but Berlin is no longer the industrial center it once was. The city of Berlin today is a bit quieter, with less than half the population of 20,000 at its peak in 1930.

A vast ATV trail network can take you from the city of Berlin to Gorham, Milan, Errol, Groveton, Stratford, Colebrook, and many other communities in North County, New Hampshire, as far as Pittsburgh.

 

Sights

Berlin, nestled in the northern part of New Hampshire's White Mountains region, is a city with a rich industrial heritage, often called "The City That Trees Built" due to its historical ties to logging and paper mills. With a population around 10,000, it sits along the Androscoggin River and serves as a gateway to outdoor adventures, including hiking, ATV trails, and winter sports. The area reflects a diverse cultural history influenced by French Canadian, Yankee, Norwegian, Italian, Irish, and Russian settlers who came for work in mills, farms, and logging camps. Today, Berlin is revitalizing with a focus on tourism, featuring natural attractions, historical sites, and community events. Its proximity to the Canadian border (about an hour away) adds a bilingual flair, with French as a common second language.

Jericho Mountain State Park
One of Berlin's premier attractions, Jericho Mountain State Park is a 7,500-acre expanse ideal for year-round outdoor enthusiasts. Established as New Hampshire's newest state park, it offers over 80 miles of well-maintained trails primarily designed for ATVs and snowmobiles, but also open to hiking, mountain biking, horseback riding, fishing, skiing, and hunting. The park includes a swimming area at Jericho Lake, camping sites, and a limited number of cabins for overnight stays. In winter, it connects to the New Hampshire Snowmobile Association corridors for extensive snowmobiling. A highlight is Jericho Falls, a scenic waterfall accessible via a short hike: start from a dirt road past a gated ATV trail and follow flagged paths for about 5 minutes. The park also features a yurt for overnight stays in its 24,000-acre wilderness area. Visitors praise its natural beauty, with opportunities to spot wildlife like moose and osprey. It's particularly popular for events like the July Jericho Mountain ATV Festival, which draws crowds for rides, vendors, and demonstrations.

Northern Forest Heritage Park
This historical park, located at 961 Main Street in the historic Brown House (which also houses the Androscoggin Valley Chamber of Commerce), celebrates Berlin's logging and lumber industry roots. It features a replica logging camp, a gift shop, and educational exhibits on the region's forest heritage. Visitors can take guided river boat tours on the Androscoggin River to learn about log drives and early industry. The park hosts events throughout summer and fall, including demonstrations of traditional logging techniques. It's a great spot for families to explore the cultural history of the Northern Forest, with rentable spaces for conferences or weddings. The site underscores Berlin's evolution from a mill town to a tourism destination, reflecting the diverse immigrant workforce that built the city.

Androscoggin River
Flowing through the heart of Berlin, the Androscoggin River is a vital natural feature offering recreational opportunities like fishing, kayaking, canoeing, and rafting. The river stretches south from Lake Umbagog Wildlife Refuge in nearby Errol, passing through scenic areas such as Thirteen Mile Woods and Pontook Dam & Wildlife Sanctuary. It's part of the Northern Forest Canoe Trail, making it ideal for multi-day paddling adventures. Scenic drives along the river often yield sightings of moose, osprey, and other wildlife. Historically, the river was central to log drives, with remnants like boom piers visible today—especially during the October RiverFire festival, where these piers are lit for a dramatic fall event. The river's banks provide peaceful spots for picnics or birdwatching, and it's a key element in Berlin's revitalized Main Street area.

Mount Forist (Mount Forest)
Overlooking downtown Berlin, Mount Forist (also called Mount Forest or "Elephant Head" by locals) is a 2,031-foot peak with challenging hiking trails leading to its summit. The hike is considered moderate to difficult, especially for novices, but rewards with panoramic views of the city, river, and surrounding mountains. Trails start from various points in town, and the summit offers spots for picnicking amid forested terrain. In fall, the foliage views are spectacular, with vibrant colors blanketing the slopes. Local tips suggest using apps like AllTrails for navigation, as paths can be steep. It's a favorite for those seeking a quick but rewarding urban-adjacent hike.

Mount Jasper
Mount Jasper is an easy-to-moderate hike starting from points like the technical high school or the top of Hillside near the cemetery. At about 1,584 feet, it features interpretive signs about the mountain's geology, glaciers, and its historical significance as a lithic source (a quarry for ancient Native American tools made from rhyolite). The trail offers stunning views of Berlin, the river, and even eagles at eye level. It's a short outing, perfect for families or those interested in archaeology, with ledges providing vantage points. Use Google Maps or AllTrails for trailheads, as access can vary.

Nansen Ski Jump and Nansen Ski Club
Berlin is home to the Nansen Ski Club, the oldest cross-country ski club in the U.S., founded in 1872. The club's trails are maintained in nearby Milan Hill State Park for winter skiing. The iconic Nansen Ski Jump, a 171-foot-tall structure built in 1938, is a historical landmark along Route 16. Once hosting Olympic trials and international competitions, it's now a preserved site symbolizing Berlin's Nordic heritage. Though no longer active for jumping, it's been restored and occasionally lit for events. In winter, the area transforms into a hub for cross-country skiing and snowshoeing, with volunteers keeping paths groomed.

Haunted legends and abandoned places

Berlin, New Hampshire, a former industrial hub nestled in the Androscoggin Valley, has a rich history tied to logging, papermaking, and early settlement that has given rise to several eerie legends and reported hauntings. These stories often stem from the town's 19th-century boom as a mill town, where harsh working conditions, accidents, and isolation in the rugged White Mountains fostered tales of restless spirits and supernatural creatures. While some accounts are rooted in historical events, others have evolved through oral tradition, blending fact with folklore. Below, I'll detail the most prominent haunted legends, drawing from local historical records and eyewitness reports.

The Brown Company House Hauntings
One of Berlin's oldest and most persistently haunted sites is the Brown Company House, located on Main Street. Built in 1852 as a day boarding house for workers at the Berlin Mills Company (later renamed the Brown Company during World War I due to anti-German sentiment), it served as lodging for log drivers and sawmill laborers during the town's early industrial era. This structure, now a museum and the home of the Androscoggin Valley Chamber of Commerce, is Berlin's oldest standing building on Main Street. Its ghosts are believed to be the spirits of those rugged workers who met untimely deaths in the dangerous mills or river drives—accidents involving machinery, drownings, or exhaustion were common in the 1800s.
Reported phenomena include unexplained loud noises, such as banging or crashing sounds resembling mill equipment, even when the building is locked and empty. Footsteps echoing through the halls are frequently heard, often ascending or descending stairs as if workers are returning from a shift. Voices, sometimes murmuring in French-Canadian accents (reflecting the immigrant workforce from Quebec), have been noted by staff and visitors. These manifestations are thought to peak during evening hours or in winter, when the isolation of the North Country amplifies the eerie atmosphere. Local historians suggest the hauntings may connect to the mill's grueling history, where overwork and poor safety led to numerous fatalities. The building's preservation as a historical site has only heightened interest, with some paranormal enthusiasts conducting informal investigations, though no definitive evidence has debunked or confirmed the claims.

Androscoggin Valley Hospital Ghosts
The Androscoggin Valley Hospital (AVH), a key medical facility in Berlin, harbors its own spectral residents tied to its past as a community lifeline in a remote, industrial area. Established in the early 20th century to serve the mill workers and their families, the hospital has seen countless births, deaths, and tragedies, including industrial accidents and epidemics. Two primary ghosts are reported here, each with distinct characteristics.
The first is the spirit of a former nurse who transferred from St. Louis Hospital and continued her duties at AVH. She is associated with the sudden, lingering scent of cigarette smoke in areas where smoking was once permitted for staff. This apparition is described as benevolent, perhaps lingering to watch over patients, with some nurses reporting a comforting presence during night shifts. The second, more distressing ghost resides on the fourth floor, manifesting as anguished cries of "Help, help, please help!" These pleas echo through corridors, often startling staff and visitors, but no source is ever found. Legends tie this to a patient who died in agony from a mill-related injury, unable to receive timely aid due to the town's isolation. Historical context points to the hospital's role during the pulp mill's heyday, when severe injuries from logging and papermaking were routine. While modern renovations have altered the building, reports persist, making AVH a focal point for local ghost stories.

The Old Gym at Berlin Junior High School
Berlin Junior High School's old gymnasium holds a chilling legend that has terrified generations of students and locals. The gym, which was the school's primary athletic space until a new one was added connecting to Hillside Elementary, features a small elevated red track encircling the upper level. The haunting centers on the ghost of a janitor (or, in some versions, a principal) who reportedly died there during a routine jog. Accounts vary: some say he suffered a fatal heart attack mid-lap, others claim he fell from the track to his death, and darker tales describe him being impaled on a sharp pole below. This event allegedly occurred decades ago, during the mid-20th century when the school was a bustling part of Berlin's community.
The spirit is said to manifest as the sound of jogging footsteps on the track, even when the gym is deserted, accompanied by labored breathing or faint voices calling out. Apparitions include a shadowy figure running endlessly or, in gruesome retellings, an impaled body briefly visible on the floor. Legend warns that the ghost seeks another victim to "replace" him, luring people to jog alone at night. This story has evolved over time, with students passing it down as a rite of passage, though no verified historical death matches the details exactly. The gym's dim lighting and creaky structure enhance the fear factor, making it a staple of Berlin's urban legends.

The Wood Devils of Coos County
Beyond urban hauntings, Berlin is near the epicenter of the "Wood Devils" legend, a folklore creature said to roam the dense forests of Coos County. These beings are described as tall, thin, hairy humanoids with grey fur, non-human faces, and piercing screams that echo through the woods. Hostile and elusive, they hide behind trees, ambushing hikers or loggers. Sightings date back to Native American times, with the Abenaki people calling similar entities "Keewakw"—half-human, half-animal predators that feed on wanderers. In Berlin's vicinity, reports include encounters on Mt. Jasper, where shadowy figures have been spotted since the 1800s.
This legend ties to the area's logging history, where isolated workers in the 19th century attributed unexplained noises and disappearances to these creatures. Modern sightings, though rare, continue, often during hikes or hunts. While skeptics attribute them to bears or imagination fueled by the remote wilderness, the Wood Devils represent Berlin's connection to ancient folklore, blending Indigenous stories with settler fears of the untamed North Country.

Abandoned Places in Berlin, New Hampshire
Berlin's decline from a thriving paper mill town—once boasting the world's largest papermaking complex—to a post-industrial community has left behind numerous abandoned sites. The closure of mills in the early 2000s, coupled with economic shifts, created vast derelict areas, some contaminated and others reclaimed by nature. These places evoke a sense of faded glory, with crumbling structures amid the scenic White Mountains. Note that many are on private property or hazardous, so exploration should be done legally and safely.

The Ruins of the Berlin Pulp Mill (International Paper Company Site)
The most iconic abandoned site in Berlin is the former Berlin Pulp Mill, a 121-acre complex along the Androscoggin River that was the heart of the town's economy for over a century. Founded as Berlin Mills Company in 1868 by W.W. Brown, it grew into a massive operation producing pulp and paper, employing thousands and fueling Berlin's population boom. Renamed Brown Company during WWI and later acquired by International Paper, the mill's decline began in the late 20th century due to corporate changes and market shifts. The pulp mill closed permanently in 2006 under Fraser Papers, with the structures—including 300-foot smokestacks—demolished in 2008 to end an era of prosperity.

Today, ruins remain: scattered foundations, rusted machinery, and remnants of the furnace system, overgrown with vegetation. The site, once emitting the infamous "smell of money" (sulfur from pulping), is now a haunting industrial graveyard, with toxic remnants like leachate posing environmental risks. Urban explorers note eerie silence broken by river sounds, and some tie it to worker ghosts from accidents. Parts have been repurposed for energy projects, but much is fenced off and abandoned.

Dummer Yard Landfill
Located on the outskirts of Berlin, the Dummer Yard Landfill is a 200-acre abandoned waste site that operated from the 1970s until its closure in 2002. Originally a disposal area for mill waste and municipal trash, it has since become a environmental hazard, generating over 4 million gallons of toxic leachate annually that seeps into nearby soil and waterways. The site's abandonment left behind mounds of debris, rusted equipment, and contaminated ponds, creating a post-apocalyptic landscape amid the forests.
Community debates rage over repurposing it as a managed soil site to cap the landfill and generate revenue, but as of 2025, it remains largely untouched, with proposals like the Dummer Yard Repurposing Project aiming to address the $20-30 million cleanup cost. Explorers describe it as desolate and foreboding, with chemical odors and wildlife avoiding the area. Its proximity to residential zones adds to local concerns, making it a symbol of Berlin's struggle with industrial legacy pollution.

Other Abandoned Structures and Sites
Berlin is dotted with lesser-known abandonments from its mill era. Scattered old mill buildings and dams, like remnants near the Androscoggin, feature crumbling stone foundations and overgrown paths, echoes of the 19th-century cloth and paper factories. Flickr photos document derelict buildings on Pleasant Street, with broken windows and graffiti, likely former worker housing or storage.
While searches mention "forgotten bunkers" in local lore (possibly cold-war era shelters or mining bunkers from Mt. Jasper's history), no verified sites exist—likely confused with other NH locations like Rye's WWII bunkers. Similarly, abandoned schools are scarce; the Brown School (built 1916) was vacant but is now apartments, and George E. Burgess School (1905) is historic but preserved. Older, unnamed schools from Berlin's early days may have ruins in wooded areas, contributing to the town's eerie, time-frozen vibe.

 

History

Origins and Early Settlement
Berlin, New Hampshire, is the northernmost city in the state and the only city in Coös County, situated along the Androscoggin River in the Great North Woods region, on the edge of the White Mountains. The area has been inhabited for millennia; around 11,000 years ago, Native Americans camped there, and later, the Eastern Abenaki tribes mined rhyolite at Mt. Jasper for tools and weapons, with artifacts now displayed at the Berlin Public Library. The name "Berlin" derives from the Old Polabian word meaning "bog" or "swamp," though the exact reason for its adoption remains unclear. The land was first granted as the township of Maynesborough on December 31, 1771, by Colonial Governor John Wentworth, named after Sir William Mayne of London. However, the original grantees failed to settle it, and claims lapsed after the American Revolution.
Exploration began in 1802 by Seth Eames and Gideon Tirrell, but permanent settlement didn't occur until 1823–1824, when William Sessions and Cyrus Wheeler from Gilead, Maine, arrived and built the first log cabin on what became Thompson Farm. Early inhabitants focused on farming, with the population reaching just 65 by 1829. That year, with help from Thomas Wheeler (Cyrus's father), the township was reincorporated as the town of Berlin on July 1, drawing settlers mostly from nearby Shelburne, NH, and Gilead, ME. A road to Gorham was built in 1826 by Thomas, Amos, and Daniel Green, and Berlin's first retail market opened in 1835 under Thomas Green. The heavily forested region and the river's falls soon highlighted potential for logging and milling over agriculture.

Industrial Boom: Logging and Pulp/Paper Mills
Berlin's transformation into "The City That Trees Built" began in earnest with the arrival of the St. Lawrence & Atlantic Railroad (later Grand Trunk) in 1851, enabling efficient transport of wood products. In 1852, businessmen from Portland, Maine—John B. Brown, Josiah S. Little, Nathan Winslow, and Hezekiah Winslow—acquired water, timber, and rail rights, forming H. Winslow & Company. They built a large sawmill at Berlin Falls, which was renamed Berlin Mills Company in 1868 after William Wentworth Brown and Lewis T. Brown gained control. By the 1880s, multiple mills operated, including the Riverside Mill (Brown Company), Forest Fibre Company (the first chemical pulp mill in Berlin, built in 1877 by H.H. Furbish), White Mountain Pulp & Paper Company, and later International Paper Company.
The industry exploded in the late 19th and early 20th centuries, with Berlin becoming home to the world's largest paper-making complex at its peak. Timber was harvested in winter camps across millions of acres (extending to Quebec and Florida), employing over 9,000 workers, and floated down the Androscoggin on spring log drives, with remnants like boom piers still visible. Innovations from Berlin included Bermico conduit pipe (1920s–1970s), cellulose floc, the Farrand Rapid Rule, iron ski rigging, Kream Krisp shortening (leading to a lawsuit against Procter & Gamble), and Nibroc Paper Towels mass-produced by inventor William E. Corbin. The Brown Company survived the Great Depression with government aid but entered receivership, changing hands multiple times post-World War II. During World War I, anti-German sentiment led to renaming Berlin Mills to Brown Company and shifting pronunciation from "Ber-LIN" to "BUR-lin."
Infrastructure grew alongside industry: Furbish installed electric streetlights in 1877 (among NH's first), a street railway to Gorham started in 1902 (peaking at 1.6 million passengers in 1920), and downtown boomed with brick buildings replacing wooden ones post-1900. Berlin incorporated as a city in 1897, with population surging from 73 in 1830 to a peak of 20,018 in 1930.

Immigration, Culture, and Community
The mills attracted waves of immigrants from the 1880s–1900s, including from Russia, Norway, Finland, Italy, Sweden, Ireland, Germany, Great Britain, and especially Quebec (French Canadians made up 57–65% of the population by 2010). Recruiters met workers at Ellis Island, leading to ethnic neighborhoods: French Canadians on Granite, School, Champlain Streets and the East Side (in multi-generational "blocks"); Germans on Goebel Street (engineers like Alfred Tupper, inventor of Tupperware); Russians influencing the 1915 Holy Resurrection Orthodox Church. Scandinavians founded the Nansen Ski Club in 1872 (America's oldest, honoring Fridtjof Nansen), building the Nansen Ski Jump in 1936 (largest in eastern U.S. until 1988, restored 2017). This diversity earned Berlin nicknames like "Paper City," "Tansy Town," and "Hockey Town USA," with strong ties to outdoor recreation and sports.
Churches reflected cultural bonds, many on the National Register: St. Anne Catholic (1901, Italian Baroque, for French Canadians); St. Kieran’s (1895, now arts center); Congregational Church; and others. Community landmarks include City Hall (1914, Georgian revival), Berlin Public Library (1903, Carnegie-funded), and the Central Fire Station (1905, Romanesque, used as WWII lookout).

Decline, Economic Shifts, and Modern Era
Post-1930, the pulp and paper industry declined amid economic pressures, with Brown Company bankrupt near WWII's end and mills sold to out-of-state owners. American Tissue's 2001 bankruptcy halted city taxes, and Fraser Papers (acquired in 2002) closed the last pulp mill in 2006, displacing 250 workers; the site was demolished and partially repurposed for a biomass plant. Population halved from its peak, dropping to 9,425 by 2020, with median household income around $35,523 and 20.3% below poverty (2011–2015 data).
Berlin pivoted to corrections: Northern New Hampshire Correctional Facility (1999, 750 beds) and Federal Correctional Institution (2012, 1,200 beds) now employ hundreds. Recreation boomed with Jericho Mountain State Park (2005, ATV trails on old rail beds) and the annual Jericho Mountain ATV Festival. Heritage preservation includes the Berlin and Coös County Historical Society's Moffett House Museum (Victorian home with artifacts, genealogy, and mill relics), restored Brown Company Barns, Service Credit Union Heritage Park, and the Berlin Fish Hatchery. Media like The Berlin Daily Sun (featuring historian Paul "Poof" Tardiff until 2018) and the defunct Berlin Reporter (1900–2024) chronicled its story. Today, Berlin reinvents itself as an adventure hub—"Your Adventure Starts Here"—blending industrial legacy with outdoor tourism.

 

Geography

Berlin, New Hampshire, is the northernmost city in the state, situated in Coos County within the North Country or Great North Woods Region. It lies along the Androscoggin River at its confluence with the Dead River, positioned on the northern edge of the White Mountains and extending into the White Mountain National Forest. The city's coordinates are approximately 44°28′07″N 71°11′02″W, with a total area of 62.2 square miles (161.1 km²), including 61.4 square miles (158.9 km²) of land and 0.8 square miles (2.2 km²) of water, accounting for about 1.37% water coverage. The urban core sits at an elevation of around 1,020 feet (310 m) above sea level, nestled in a river valley surrounded by rugged, forested terrain. Nearby attractions include Milan Hill State Park to the north and Jericho Mountain State Park to the west, which features a man-made reservoir from the 1970s and extensive ATV trails.
This setting places Berlin in a transitional zone between the densely wooded Great North Woods to the north and the more dramatic alpine landscapes of the White Mountains to the south, making it a gateway for outdoor recreation.

 

Topography and Physical Features

Berlin's topography is characterized by hilly to mountainous terrain shaped by glacial activity, with elevations ranging from about 734 feet (224 m) in the river valleys to 3,901 feet (1,189 m) at Mount Weeks, the city's highest point. A prominent local landmark is Mount Forist, rising to 2,031 feet (619 m) on the west side of the city, offering panoramic views of the urban area below. The Mahoosuc Range extends to the southeast, contributing to the rugged profile, while the city's boundaries incorporate portions of the White Mountain National Forest, which dominates the southern and eastern fringes.
The landscape features a mix of broad river valleys, steep slopes, and scattered hilltops where bedrock often protrudes through thin soil layers. Approximately half of Berlin drains into the Androscoggin River watershed (which ultimately flows into the Kennebec River in Maine), while the other half contributes to the Connecticut River watershed via tributaries like the Upper Ammonoosuc River. This dual watershed dynamic influences local hydrology and ecology. The southern part of the city includes the village of Cascade, known for its industrial heritage along the river.

 

Rivers and Water Bodies

The Androscoggin River is the defining hydrological feature of Berlin, flowing through the city and historically powering its pulp and paper industries with its falls and rapids. The river's confluence with the Dead River creates a dynamic aquatic environment, supporting fisheries and recreational activities like kayaking and fishing. Smaller tributaries, such as Moose Brook, Peabody River, and Moose River, feed into the Androscoggin, forming alluvial fans and terraces along the valley floors. These streams have incised channels over time, exposing gravelly deposits and creating flat-topped terraces elevated above current floodplains.
Water bodies are limited, with no major natural lakes, but man-made features like the Jericho Lake reservoir add to the area's appeal. Wetlands, including organic-rich marshes in small basins, dot the landscape, particularly in meltwater channels east of the Moose River valley.

 

Geology

Berlin's geology is dominated by surficial deposits from the Pleistocene and Holocene epochs, overlying Precambrian to Paleozoic bedrock of igneous and metamorphic origins. The area was covered by the Laurentide Ice Sheet around 25,000 years ago, with ice flow directed east-southeast to south-southeast. Deglaciation occurred before 14,000 years ago through retreat and thinning, leaving behind a variety of glacial features.
Key deposits include:

Till: The most extensive, a poorly sorted mix of sand, silt, gravel, and boulders, up to 217 feet (66 m) thick in valleys, blanketing hillsides and often absent on exposed hilltops.
Eskers and Ice-Contact Deposits: Ridges and pits of coarse gravel and sand from subglacial meltwater, notable along the Androscoggin Valley.
Glacial Outwash and Deltas: Terraces and small deltas (e.g., at ~1,040 feet elevation south of Moose Brook) formed in temporary glacial lakes.
Postglacial Features: Alluvial fans from tributaries like the Peabody and Moose Rivers, composed of boulder gravel; stream terraces; and a notable landslide zone southwest of Gorham with deep-seated failures exposing up to 50 feet (15 m) of diamicton.
Other: Wetlands with organic sediments and artificial fill along infrastructure.

This glacial legacy has created a landscape prone to erosion and landslides, with striated boulders and streamlined till ridges evidencing past ice movement. No major end moraines are present in the southern half of the Berlin quadrangle, though small segments exist nearby.

 

Climate

Berlin experiences a warm-summer humid continental climate (Köppen Dfb), marked by significant seasonal variations, cold and snowy winters, and relatively mild summers. The proximity to the White Mountains influences local weather patterns, with orographic effects contributing to higher precipitation in certain areas.
