Located at the corner of Bow and Walnut streets in Somerville’s Union Square commercial center, the former Prospect Hill Congregational Church is one of the finest examples of the Richardsonian Romanesque style in the city. The congregation here was established in 1874 and originally met in private residences before erecting its first building on Warren Street in 1876. After two decades, the membership and prosperity of the congregation grew, allowing it to purchase a more prominent lot nearby and the ability to hire an architect for a new, substantial building. Architect Henry Squarebridge McKay furnished plans for the masonry building in 1887, clearly taking inspiration from the late Henry Hobson Richardson, who died the year prior. The church is constructed of brick with stone trimmings, features irregular massing with tall belfry tower, and a large arched entrance. After WWII, the congregation dwindled, and the building was later sold off. In the 1980s, the church was converted to residential use but without altering the exterior.
