Cambridge is a city in Massachusetts, across the Charles River from Boston. It’s home to Harvard University, which has been a fixture in the area since 1636, when Puritan minister John Harvard left his library and half of his estate to start a new school.

At the heart of campus, grassy Harvard Yard is anchored by the neoclassical Widener Library. Harvard Square has cafes, bars and bookstores. The Harvard Art Museums comprise the Fogg, Busch-Reisinger and Arthur M. Sackler collections. Southeast is the prestigious Massachusetts Institute of Technology (MIT).

Cambridge was founded in 1630 as "Newtowne," but was rechristened after King Charles II granted it a charter in 1685. The city's population grew steadily throughout the 19th century until it peaked at 100,000 in 1950; since then, it has shrunk by about 20 percent due to suburbanization and other factors leading to urban decline like crime rates.

Cambridge has about 117,822 people living there as of 2020.
