The city of Cambridge is part of the Greater Boston area of Massachusetts. The city is best known for being the home of two world-class universities, Harvard University and Massachusetts Institute of Technology (MIT), located within just two miles of each other. Cambridge is bordered by the city of Boston, located on the other side of the Charles River just 3 miles to the southeast. Other surrounding communities include Somerville (to the north), Watertown (to the west), and Arlington (to the northwest). The city's major industrial focus in the nineteenth and early twentieth centuries centered on factories (largely furniture and glass) but since that time, the emphasis has shifted to technology-based enterprises, including electronics, software, and biotechnology research.
Cambridge today is very much a college-influenced community combining a strong mix of cultural and social diversity, intellectual vitality, and technological innovation.
