Union Square is a neighborhood in the southeastern part of Somerville, Massachusetts, United States. It is centered on Union Square proper, which is located at the intersection of Washington Street, Webster Avenue, and Somerville Avenue.
The name "Union Square" comes from the square having been used as a recruitment and mustering site for the Union Army in the Civil War. A plaque commemorating the mustering site sits at the southwestern corner of the square between Somerville Avenue and Washington Street, and the Prospect Hill Monument is located several blocks away atop Prospect Hill. Union Square is now the commercial center of a primarily residential neighborhood with many restaurants, bars and neighborhood stores.
As the oldest and largest commercial area in the city, Union Square is home to a number of community institutions, including the Somerville Police headquarters, Somerville Community Access Television (SCATV), and Boston Free Radio.[1]
