Cambridge is a city located in Middlesex County in the state of
Massachusetts, United States. In the 2020 Census it had a
population of 118,403 inhabitants and a population density of
7,182 people per km². It is located in the eastern part of the
state, on the outskirts of Boston.
Cambridge is known for
being home to Harvard University and the Massachusetts Institute
of Technology (MIT). According to the 2000 census, the city has
a population of 101,355, although many more people go to
Cambridge to work.
Cambridge's population is very diverse. Its residents, known as
"cantabrigians" (in Spanish it would be cantabrigiense), range from
distinguished professors from MIT and Harvard to working-class families,
including immigrants from around the world. The first same-sex civil
union in the United States was held at Cambridge City Hall.
This
diversity contributes to the liberal environment and can be compared to
Berkeley, California in some ways. This, along with historic student
protests and a rejection of legal rent control, has earned it the
humorous label of the "Cambridge People's Republic." Cambridge is today
an urbanally renewed, upper-middle-class city with a growing property
market, just across the river from Boston. It is also known as the
"Boston Left Bank".
Cambridge has also been called by some the
"city of squares" ("City of Squares" in English), since most of its
commercial districts are large intersections known as squares. In the
New England region, the term square is applied to a commercial area,
usually formed around the intersection of three or more streets, and
originally consisting of a cleared square area. Since most of the
streets were built centuries ago, only a few squares retain the
geometric shape of a square. Harvard Square is, for example, formed by
two converging curved streets. Each of these squares serves as a
neighborhood center. These include:
Kendall Square, formed by the
intersection of Broadway, Main Street and Third Street, after the
Longfellow Bridge that connects Cambridge with Boston, and at the
western end of the MIT campus. In its surroundings is the Kendall
station on the red line of the subway. Most of Cambridge's large office
skyscrapers are located here, and a thriving biotech industry has grown
in the surrounding area.
Central Square, formed by the intersection
of Massachusetts Avenue, Prospect Street and Western Avenue. It is
perhaps the closest to a financial and commercial center in Cambridge,
and is well known for its wide variety of ethnic restaurants. In the
1990s it was partly dismantled and the area underwent controversial
urban renewal in recent years and continues to increase in value. In its
surroundings is the metro station of the same name. Lafayette Square,
formed by the intersection of Massachusetts Avenue, Columbia Street,
Sidney Street, and Main Street, is considered part of the Central Square
area.
Harvard Square, formed by the intersection of Massachusetts
Avenue, Brattle Street, and JFK Street. Here is located Harvard
University, the oldest university in the United States, and a major
shopping area in Cambridge. In its surroundings is the metro station of
the same name. The north section of Harvard east of Massachusetts Avenue
is known as Agassiz, after famed scientist Louis Agassiz.
Porter
Square, about one mile north of Massachusetts Avenue from Harvard
Square, formed by the intersection of Massachusetts and Somerville
avenues, and includes part of the city of Somerville. In its
surroundings is the Porter metro station.
Inman Square, at the
intersection of Cambridge and Hampshire streets, in the center of
Cambridge. In this square are located various restaurants, bars and
boutiques.
Lechmere Square, at the intersection of Cambridge and
First streets, adjacent to the CambridgeSide Galleria shopping centre.
It is known for being there the terminal station of the green line of
the metro.
Among the residential neighborhoods are Cambridgeport,
west of Central Square, toward the Charles River; Riverside, south of
Massachusetts Avenue toward the Charles River, between Central and
Harvard Square; East Cambridge; Wellington-Harrington; North Cambridge;
Agassiz; Avon Hill; Brattle Street; Strawberry Hill; and Mid Cambridge,
bounded by Central, Harvard, Inman Square, and the city of Somerville.
On the west bank of Cambridge, Mount Auburn Cemetery is known for
its burials of distinguished people, magnificent landscaping, and
outstanding arboretum.
Although you often see references to the
"Boston/Cambridge area" in the press, Cambridge prefers to retain its
own identity.
Pre-Colonial and Indigenous History
The area now known as
Cambridge, Massachusetts, has been inhabited for thousands of years.
Archaeological evidence indicates human occupation dating back 11,000 to
13,000 years, following the retreat of the last continental ice sheets.
The landscape featured steep hills, islands, vast salt marshes, and
tidal streams, supporting a seasonal population of Algonquian-speaking
peoples, including the Massachusett tribe. They lived in the region
called Anmoughcawgen, meaning "fishing weir" or "beaver dam" in the
Natick dialect. The Naumkeag or Pawtucket lived to the north, and the
Massachusett to the south, with possible overlap from other groups like
the Totant. These indigenous groups engaged in hunting, fishing,
shellfish harvesting, crop cultivation (such as corn, beans, and
squash), and established footpaths connecting settlements, river
crossings, and hunting grounds. European contact in the early 17th
century introduced infectious diseases, leading to virgin soil epidemics
that decimated native populations—reducing them by up to 90% in some
areas—leaving the land largely uncontested by the time English settlers
arrived in 1630.
The Massachusett tribe's female chief, known as the
Squaw Sachem of Mistick, lived near the confluence of Alewife Brook and
the Mystic River. In 1640, the English colonists secured a deed from her
for the land occupied by Cambridge and Watertown, paying her about £23
and providing an annual coat during her lifetime. This transaction
formalized European claims over indigenous territories that had already
been weakened by disease and tribal conflicts.
Founding and
Colonial Period (1630–1775)
Cambridge was founded in December 1630 as
part of the Massachusetts Bay Colony by a group of Puritan settlers led
by Deputy Governor Thomas Dudley, his daughter Anne Bradstreet
(America's first published poet), and son-in-law Simon Bradstreet.
Initially called "the newe towne" (later Newe Towne by 1632 and Newtowne
by 1638), it was selected as the colony's intended capital due to its
defensible position upriver from Boston Harbor, about five miles
upstream on the north bank of the Charles River. The site offered
protection from potential naval attacks and access to fresh water. The
first houses were constructed in the spring of 1631, and the settlement
was laid out in an orderly grid pattern—bounded today by Eliot Square,
Linden Street, Massachusetts Avenue, and the Charles River—making it one
of the first planned communities in New England with house lots,
planting fields, and common land allocated to families.
The Puritans,
fleeing religious persecution in England, aimed to establish a community
centered on a "purer" Biblical church. By 1636, the town had a
meetinghouse, a school, and a marketplace at Winthrop Square. In 1636,
the Great and General Court established Harvard College (initially New
College) to train ministers and leaders, making it the oldest
institution of higher education in the United States. Key early figures
included preacher Thomas Hooker (who later led settlers to found
Hartford, Connecticut, in 1636), Thomas Shepard, Harvard's first
president Henry Dunster, benefactor John Harvard (who donated his
library and half his estate in 1638, leading to the college's renaming),
and schoolmaster Nathaniel Eaton. Governor John Winthrop, who signed the
Cambridge Agreement in 1629 for the colony's charter, was also
influential. In 1638, the town was renamed Cambridge after the
University of Cambridge in England, reflecting the settlers' educational
aspirations. In 1639, the court purchased additional land from the Squaw
Sachem.
The town grew slowly as an agricultural village, about eight
miles from Boston by road (via a ferry at the foot of present-day JFK
Street and a path through Brookline and Roxbury). A "pallysadoe"
(stockade fence and trench) was built for defense. By 1650, Governor
Thomas Dudley signed Harvard's charter. Cambridge's boundaries were
larger then, including areas that later became independent towns:
Cambridge Village (Newton) in 1688, Cambridge Farms (Lexington) in
1712–1713, and Little or South Cambridge (Brighton) and Menotomy or West
Cambridge (Arlington) in 1807. The population was mostly Puritan
descendants—farmers, artisans, and tradesmen—focused on village life,
with a small elite of Anglican "Tories" living in mansions along Brattle
Street (Tory Row). Proposals to annex Cambridge to Boston in the late
19th century were rejected.
Revolutionary War Era (1775–1783)
By the time of the American Revolution, Cambridge was a quiet farming
village clustered around the Common and Harvard College. On April 18,
1775, William Dawes rode out Massachusetts Avenue en route to Concord to
warn of British movements. The next day, four Cambridge patriots died in
a skirmish with retreating British troops at Massachusetts and Rindge
Avenues following the Battles of Lexington and Concord. In May 1775,
about 16,000 American patriots assembled on Cambridge Common to organize
against the British, marking it as the birthplace of the Continental
Army.
On July 2, 1775, George Washington arrived at Cambridge Common
to take command of the newly formed Continental Army, two weeks after
its establishment by the Second Continental Congress. Washington
headquartered at the Vassall-Craigie-Longfellow House (now a National
Historic Site) for nine months from July 1775 to April 1776 during the
Siege of Boston. He oversaw the construction of three earthen forts
along the Charles River, with remnants of Fort Washington still visible
in Cambridgeport. On January 24, 1776, Henry Knox arrived with artillery
captured from Fort Ticonderoga, bolstering the siege and forcing the
British evacuation of Boston in March 1776. After the war, many Loyalist
estates were confiscated, and Cambridge's Tory elite largely fled.
Industrial Era and 19th Century (1790–1900)
Cambridge transformed
rapidly between 1790 and 1840 with infrastructure improvements. The West
Boston Bridge (now Longfellow Bridge) opened in 1793, shortening the
distance to Boston from eight to three miles and spurring development in
Cambridgeport along Massachusetts Avenue, where Central Square became
the commercial hub. The Canal Bridge (near the Museum of Science) opened
in 1809 alongside the Middlesex Canal, and turnpikes like the Cambridge
and Concord Turnpike (now Broadway and Concord Avenue) and Middlesex
Turnpike (Hampshire Street and Massachusetts Avenue) were built.
Railroads, including the Boston & Maine, connected the area, leading to
Somerville's separation from Charlestown. These changes converted
estates and marshland into industrial and residential districts.
Cambridge incorporated as a city in 1846, uniting Old Cambridge (rural
and academic), Cambridgeport (residential and commercial), and East
Cambridge (industrial). East Cambridge developed after 1809, becoming
the city's industrial center with furniture factories, glassworks (like
the New England Glass Company, 1818–1888, later moved to Toledo), and
brickyards. Andrew Craigie donated land for the Middlesex County
courthouse in 1813. Industries included ice-cutting on Fresh Pond by
Frederic Tudor and confectionery firms along "Confectioner's Row" on
Main Street. Population grew from about 1,582 in 1764 to over 52,000 by
1900.
Immigration surged, especially after the 1845 Irish Potato
Famine, with Irish settling in East Cambridge and North Cambridge,
working in factories and brickyards. By 1855, 22% of East Cambridge
adults were Irish-born, forming tight-knit Catholic communities.
Abolitionists like William Lloyd Garrison and writer Margaret Fuller
lived in Cambridgeport; Richard Henry Dana (author of Two Years Before
the Mast) grew up there. African Americans, present since colonial
times, benefited from integrated schools, attracting families from
Boston. Notable figures included Harriet Jacobs (author of Incidents in
the Life of a Slave Girl), who ran a boarding house in the 1870s, and
educator Maria Baldwin, the first African American headmaster in the
North in 1889.
Key institutions expanded: Radcliffe College (for
women) founded in 1879 (merged with Harvard in 1999); Mount Auburn
Cemetery in 1831; churches like Christ Church (1760) and Sacred Heart
Catholic Church (1874); bridges like Harvard Bridge (1890) and
Longfellow Bridge (1907); and the Charles River Dam (1910). Old
Cambridge retained its rural charm, home to literary figures like Henry
Wadsworth Longfellow, James Russell Lowell, and William Dean Howells.
20th Century and Modern Developments (1900–Present)
By 1920,
Cambridge was a major industrial city with nearly 120,000 residents,
featuring companies like Carter's Ink, Athenaeum Press, and candy makers
(e.g., Necco, Squirrel Brands, originators of Fig Newton, Charleston
Chew, and Junior Mints). Around 1900, immigrants from Italy, Poland,
Portugal, French Canada, and Russia arrived, settling in Cambridgeport,
East Cambridge, and North Cambridge. However, heavy industry declined
during the Great Depression and post-World War II, shifting Cambridge
toward an intellectual and innovation hub. The Massachusetts Institute
of Technology (MIT) relocated from Boston in 1916, reinforcing this
transition. Population peaked at 120,740 in 1950 but declined as
families moved out, giving way to singles and couples.
Racial
dynamics included segregation in public housing: In 1935, the Cambridge
Housing Authority demolished an integrated tenement, building
whites-only Newtowne Court (1940) and blacks-only Washington Elms.
Harvard and Radcliffe grew influential, with Harvard as a major
landowner. The 1980s saw a high-tech boom in Kendall Square, dubbed "the
most innovative square mile on the planet" since 2010, hosting startups
and offices for Google, Microsoft, Amazon, and Akamai. Software pioneers
like VisiCorp (VisiCalc) and Lotus Development emerged, later
overshadowed by Microsoft. Biotechnology flourished after a 1976
moratorium on recombinant DNA experiments led to 1977 regulations,
enabling companies like Biogen (1982), Genzyme, Novartis, Moderna, and
Editas Medicine.
Rent control (until repealed in 1994) supported
diverse incomes but led to housing shortages; repeal spurred a 50%
increase in construction, tripled permit revenue, and raised property
values by $7.8 billion. Cambridge became a sanctuary city in 1985
(reaffirmed 2006). Today, with over 100,000 residents from diverse
backgrounds, it hosts Harvard, MIT, Lesley University, and Cambridge
College. Population stabilized post-2008 housing bubble due to amenities
and Boston proximity. Modern landmarks include MIT buildings (from
1913), subway stations like Central Square (1912), and parks like Jill
Brown-Rhone Park (2007). Cambridge remains a center for education, tech,
and biotech, blending historic charm with innovation.
Cambridge is a vibrant city located in Middlesex County, eastern Massachusetts, United States. Situated on the north bank of the Charles River, it lies directly across from Boston, forming part of the greater Boston metropolitan area. The city serves as a key suburb of Boston and is renowned for its academic institutions, including Harvard University and the Massachusetts Institute of Technology (MIT). Geographically, Cambridge covers a total area of approximately 7.13 square miles (18.47 km²), with 6.43 square miles (16.65 km²) of land and 0.71 square miles (1.83 km²) of water, representing about 10% water coverage. Its coordinates are roughly 42°22′N latitude and 71°6′W longitude, placing it in a strategic position along the Atlantic coastal plain.
Cambridge's topography is predominantly flat to gently rolling,
characteristic of the Boston Basin region, with an average elevation of
about 39 feet (12 meters) above sea level. Some sources note an average
elevation closer to 36 feet (11 meters), reflecting minor variations
across the landscape. The terrain is influenced by its glacial history,
featuring low-lying areas near the Charles River and slightly higher,
hilly sections in the northwest and southwest parts of the city. These
hills, part of the broader Boston Basin Hills, include modest rises that
provide subtle topographic relief, such as those around Fresh Pond and
the Alewife Brook area.
The city's landscape has been significantly
altered by human activity, including land filling and urban development.
Much of the eastern and southern portions were historically marshy or
tidal flats, which have been filled over centuries to accommodate
growth. Today, Cambridge is densely urbanized, with a mix of
residential, commercial, and institutional land uses. Open spaces are
limited but include parks like the Charles River Reservation and Fresh
Pond Reservation, which offer recreational green areas amid the built
environment. The city's proximity to sea level makes it vulnerable to
flooding, with about 42% of buildings at risk, exacerbated by climate
change.
The Charles River is the defining hydrological feature of Cambridge,
forming its southern boundary and separating it from Boston. This
80-mile-long river flows into Boston Harbor and has historically been
central to the city's development, transportation, and recreation.
Cambridge obtains much of its water supply from upstream sources like
Hobbs Brook in nearby Lincoln and Waltham. Other notable water bodies
include Fresh Pond, a 155-acre reservoir in the northwest that serves as
a primary drinking water source and is surrounded by protected parkland,
and Alewife Brook, which drains into the Mystic River to the north.
The city's hydrology is intertwined with its urban infrastructure,
including stormwater management systems to handle heavy precipitation.
Due to its low elevation and coastal influence, Cambridge faces
increasing risks from sea-level rise, storm surges, and precipitation
extremes, prompting initiatives for resilience and flood mitigation.
Geologically, Cambridge sits within the Boston Basin, a region shaped
by ancient sedimentary deposits and glacial activity. The bedrock
primarily consists of the Cambridge Formation (also known as Cambridge
Argillite or Slate), a dense argillaceous rock from the late Precambrian
to early Cambrian period, over 500 million years old. This formation is
part of a suite of rocks deposited in an ancient shallow sea environment
more than 250 million years ago, later folded and faulted during
tectonic events like the collision of North America and Africa around
300 million years ago.
Overlying the bedrock are glacial deposits
from the last Ice Age, including till, outwash, and moraines that
sculpted the current landscape. The area around Mystic Lakes and Fresh
Pond exemplifies glacial geology, with features like kettles and eskers
formed by retreating glaciers about 12,000-15,000 years ago. Soils are
generally loamy and conducive to grass, supporting limited natural
vegetation in urban parks. The post-glacial rising sea levels have
influenced the coastal and riverine areas, contributing to the marshy
lowlands that were later filled.
Cambridge experiences a humid continental climate (Köppen classification Dfa), characterized by four distinct seasons: warm, humid summers; mild springs and falls; and cold, snowy winters. Average annual temperature is around 50.1°F (10.1°C), with temperatures ranging from lows of 19°F (-7°C) in January to highs of 84°F (29°C) in July. Precipitation is fairly evenly distributed throughout the year, totaling about 46-49 inches (1,174 mm) annually, including significant snowfall in winter (around 50-60 inches on average).
Cambridge is divided into 13 distinct neighborhoods, each with unique
characteristics: East Cambridge, Area 2/MIT, Wellington-Harrington, The
Port (formerly Area IV), Cambridgeport, Mid-Cambridge, Riverside,
Agassiz, Neighborhood Nine, West Cambridge, North Cambridge, Cambridge
Highlands, and Strawberry Hill. These areas reflect a blend of
residential, industrial, and academic zones, with squares like Harvard
Square and Central Square serving as cultural and commercial hubs.
The city's geography supports a high population density of about 18,000
people per square mile, totaling around 118,000 residents. Vegetation is
urban-adapted, with tree-lined streets and parks providing canopy cover.
Overall, Cambridge's geography combines natural riverine beauty with
intensive urban development, making it a dynamic part of New England's
coastal landscape.
