Union Square is a neighborhood of Somerville, Massachusetts located in the southeastern part of the city about half a mile from Inman Square in neighboring Cambridge. Located at the intersection of Washington Street, Bow Street 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 American Civil War. A plaque commemorating the mustering site sits at the southwest corner of the square between Somerville Avenue and Washington Street. Union Square is now the commercial center of a primarily residential neighborhood with many restaurants, bars and neighborhood stores.
