Hamar is a town and municipality in Hedmark which is the county
capital of Innlandet county. It borders in the west to Ringsaker, in
the northeast to Åmot, in the east to Løten, and in the south to
Stange. Closer to 223 km², or approx. 64%, of the municipality is
owned by Vang Almenning. Hamar is the largest city in the Inland,
and the municipality had 31,369 inhabitants as of 1 January 2020.
The town of Hamar had 28,434 inhabitants as of 1 January 2020 and is
part of the Mjøsby region.
The city is the county
administrative seat for Innlandet county. Norsk Tipping is
headquartered in Hamar.
The city was one of the host cities
during the Olympics in Lillehammer in 1994. The ice skating races
were held in Vikingskipet, while short track races and figure
skating took place in Hamar Olympic amphitheater, and the city
hosted several major theater and cultural events.
The ice
hockey team Storhamar Hockey, the football teams Ham-Kam and Fart
and the handball team Storhamar come from Hamar.
The city has
a rich cultural life, with active choirs, theater groups and sports
teams at all levels and a varied offer of concerts, theater
performances, film screenings and art exhibitions offered to the
region's inhabitants. The proximity to Lake Mjøsa makes the town an
attractive summer town.
Prehistory and Early Development (c. 500–1150 CE)
Evidence of
early settlement centers around the Åker farm near modern Hamar, which
served as a power center between roughly 500 and 1000 CE. Coins
inscribed "Olafr a Hamri" (referring to Hamar) from the reign of King
Harald Hardråde (Harald Hardrada, 1046–1066) have been found, indicating
activity during the late Viking Age.
Following Norway's
Christianization around 1030 (after the Battle of Stiklestad), Hamar
grew as a hub for trade and religion. The settlement shifted from Åker
to the Hamar farm (named from Old Norse Hamarr, meaning "rocky hill" or
"steep slope") around 1050 as a kjøpstad (market town). The center later
moved to the Domkirkeodden peninsula in Rosenlundvika, possibly
influenced by Harald Hardråde's landholdings there.
Medieval
Founding and Golden Age (1152–Early 14th Century)
The pivotal moment
came in 1152, when papal legate Nikolaus Breakspear (later Pope Adrian
IV) established the Diocese of Hamar as one of five medieval Norwegian
dioceses. It encompassed much of modern Hedmark, Oppland, and parts of
Buskerud, separated from the Diocese of Oslo. The first bishop was
Arnold, previously from the Greenland diocese of Garðar.
Bishop
Arnold initiated construction of Hamar Cathedral (Christ Church) on
Domkirkeodden. It began in Romanesque style around 1152–1153 and was
largely completed by ~1200, with Gothic expansions in the 14th century;
full completion is sometimes dated to ~1252 under Bishop Paul. The
cathedral became the region's most important religious site between Oslo
and Trondheim, accompanied by a bishop's residence/fortress (Hamarhus),
a chapter of canons, a school, a Dominican priory (St. Olaf's), and a
monastery of the Canons Regular of St. Anthony. The medieval urban
settlement, known as Hamarkaupangen (or Hamar Kaupangen), included
merchants, craftsmen, fishermen, orchards (famous for apples), and
supporting structures.
At its peak in the early 14th century, Hamar
featured a vibrant ecclesiastical and commercial community. Key figures
included Bishop Thorfinn (1278–1282), who was exiled and later
canonized, and a provincial council was held there in 1380. The primary
historical source is the anonymous 16th-century Hamar Chronicle
(Hamarkrøniken).
Recent archaeology (2025) has confirmed the location
of the lost urban core of Hamarkaupangen east of the cathedral and
episcopal residence, in the Kringkastingsjordet area. Using
ground-penetrating radar (GPR) since ~2023 (led by NIKU archaeologists
including Monica Kristiansen, Jani Causevic, and Ole Fredrik Unhammer),
followed by excavations starting in late June 2025, researchers
uncovered timber walls, floorboards, buildings, streets, and passageways
under layers of cooking stones. This inland medieval town (one of
Norway's eight documented medieval towns) was likely founded in the
mid-11th century during Christianization; radiocarbon dating of timbers
was underway as of 2025 to refine timelines.
Decline and
Abandonment (1349–17th Century)
The Black Death (1349) devastated the
population and economy. The Reformation (1536–1537) dissolved the
Catholic diocese; the last bishop, Mogens Lauritssøn (1513–1537), was
imprisoned at Hamar by Danish forces and died in captivity in Denmark in
1542. The cathedral ceased functioning as a bishop's seat.
In 1567,
during the Northern Seven Years' War, Swedish forces besieged the town,
blew up parts of the bishop's palace, and set fire to the cathedral,
leaving major ruins. By 1587, market privileges shifted to Christiania
(Oslo), leading to the effective abandonment of Hamar as an urban center
by the late 17th century. The area reverted to farmland under Storhamar
farm; Hamarhus became private property (e.g., under Hannibal Sehested in
1649) and later part of agricultural estates.
The cathedral ruins
(with surviving walls, primarily foundations/basements) and bishop's
residence ruins were later incorporated into 18th–19th-century farm
structures. In 1998, the "Hamardomen" (Glass Cathedral), a
steel-and-glass enclosure by architect Kjell Lund, was completed to
protect and display the ruins, also serving for concerts and events.
19th-Century Revival and Growth (1848–1900)
Interest in
re-establishing a town on Mjøsa revived in the 19th century due to
steamship trade and harbor potential. After debates and commissions
favoring other sites (like Lillehammer), King Oscar I signed a law on 26
April 1848 establishing Hamar as a kjøpstad on the Storhamar and Holset
farm grounds, with a 5 km trading monopoly zone. It was formally founded
and separated from Vang Municipality on 21 March 1849, with an initial
grid plan by engineer Røyem (Strandgata, Torggata, etc.), parks, and
public buildings.
Growth was rapid: 10 insured houses by late 1849,
31 by 1850, 56 by 1853; harbor development, a canal (1857), and
institutions followed. A major flood in 1860 caused damage. The Diocese
of Hamar was re-established in 1864 (Church of Norway), and the new
Hamar Cathedral (a long-church) was consecrated in 1866. Fires in the
1870s–1880s prompted professional firefighting. Population and area
expanded via annexations. A coat of arms (black grouse on pine) was
granted in 1896, drawing from the 1553 Chronicle.
20th–21st
Centuries: Wars, Olympics, and Modern Era
Hamar saw limited direct
WWII action, but nearby Elverum briefly became the seat of Norway's king
and parliament in April 1940 during the German invasion. Post-war
municipal mergers significantly expanded Hamar (e.g., large parts of
Vang in 1946 and 1992, Furnes in 1947, Ringsaker parts in 1965),
boosting population to over 25,000 today.
The city became a sports
hub with venues built for the 1994 Winter Olympics: Vikingskipet (Viking
Ship Hall) for speed skating and bandy, and the Hamar Olympic
Amphitheatre for figure skating and short track. It has hosted events
like the Bandy World Championship (1993), Speedway Grand Prix, Rally
Norway, and The Gathering LAN party.
Today, Hamar is a railway
junction, cultural center (with Hedmark Museum at Domkirkeodden
showcasing Viking-to-modern exhibits), and tourist destination focused
on its medieval heritage, Olympic legacy, and Lake Mjøsa setting. It
features twin towns internationally and cultural references in
literature (e.g., Sigrid Undset) and music.
Hamar is a town and the administrative center of Hamar
Municipality in Innlandet county (formerly Hedmark), in the
traditional Hedmarken district of Eastern Norway (Østlandet). It
lies on the eastern shore of Lake Mjøsa, Norway's largest lake, at
coordinates 60°47′40″N 11°04′05″E, approximately 100 km north of
Oslo. The town occupies the southwestern part of the municipality,
with its urban area (about 14.21 km²) extending slightly into
neighboring Ringsaker and Stange municipalities. It sits on a
peninsula jutting into Rosenlundvika (now associated with
Domkirkeodden), oriented toward the lake shore, which has shaped its
historical development, trade, and urban planning.
The town's
elevation is low-lying, around 127–141 meters (417–463 ft) above sea
level, with the Hamar II weather station at 141 m. The immediate
terrain is hilly rather than flat; 19th-century town planners in the
1840s struggled with a rigid grid layout because of the undulating
landscape on former farmlands like Storhamar and Holset along the
shore. Surrounding areas feature rolling hills and higher elevations
(topographic averages for broader maps around Hamar range from ~267
m to higher in some depictions), transitioning into fertile
agricultural lowlands and, farther out, parts of the broader Østland
region's plateau-like uplands grooved by valleys.
Lake Mjøsa is
central to Hamar's geography. It is a glacial fjord lake
(originating from glacial modification of a structural depression)
with a surface area of ~365–369 km², maximum length 117 km, maximum
width around 9–15 km (varying by section), average depth 150–153 m,
maximum depth 449–453 m, and water volume ~56 km³. Its surface
elevation is 119–123 m, with much of the deeper basin below sea
level. The lake stretches north-northwest to south-southeast from
Minnesund (south, near Eidsvoll) to near Lillehammer (north),
placing Hamar on its eastern shore roughly toward the
southern-central or mid-section, near one of its wider points.
Gjøvik lies opposite on the west.
Major inflows include the
Gudbrandsdalslågen river from the north (draining the Gudbrandsdalen
valley), plus tributaries like Brumunda, Flagstadelva, and others.
The primary outflow is the Vorma river southward, eventually feeding
the Glomma. The catchment area is large (~16,564 km²). Mjøsa has a
shore length of ~341 km, features the island Helgøya (largest) and
smaller islets like Steinsholmen (with medieval ruins), and supports
20 fish species (e.g., pike, perch, hundertrout). It provides
drinking water to several municipalities including Hamar and serves
as a key historical transport and trade route.
Surrounding
geography includes some of Norway's most fertile grainlands in
rolling agricultural areas around the lake, with mountains defining
parts of the shores. To the north lies the Gudbrandsdalen valley;
the broader region features glacial deposits, fertile plains in
Hedmarken, and transitions to higher forested or plateau terrain.
Historical orchards (notably apples) thrived in the medieval period,
and pine trees are notable (reflected in the coat of arms depicting
a black grouse in a pine).
Hamar has a humid continental climate
(Köppen Dfb) with cold, fairly dry winters and warm summers. At the
Hamar II station: January mean daily maximum ~−2.9°C, July ~22.5°C;
record high 33.0°C (2018), record low −29.8°C (2010); annual
precipitation ~500 mm over ~101 days. Winters can be severe
historically (e.g., −17°C monthly means in extreme years), and
summers comfortably warm. The lake moderates temperatures somewhat
but also influences local microclimates and fog.
Hydrology has
significantly influenced the town. Seasonal water level fluctuations
in Mjøsa complicated early harbors; a canal and basin were built
~1857 for better access. Flooding has been a recurring issue—e.g.,
major spring flooding in 1860 inundated streets, with additional
flash floods. Dams on the Vorma have raised levels by ~3.6 m
historically, affecting shorelines.
Urban geography reflects
adaptation to the terrain and lake. The 1848–1849 plan by engineer
Røyem imposed a grid with three main thoroughfares (Strandgata along
the shore, Torggata, Grønnegate), parks, squares (Stortorget and
Østre Torg), and a church site outside initial borders. Creeks were
crossed, and a promenade led from the harbor north. Modern features
include pedestrian zones, an underground carpark under Østre Torg,
and extension across municipal lines. Density is ~2,113/km². The
medieval predecessor was at Domkirkeodden peninsula (ruins of
cathedral, bishop's manor, fortress), now a key historical site with
the Hedmark Museum.
