Cambridge, Massachusetts City Hall

Cambridge City Hall is a town hall in Cambridge, Massachusetts, located at 795 Massachusetts Avenue. The structure was built from granite and brownstone, standing three stories tall with a 158-foot tower that rises above the surrounding streetscape.

The structure was completed in 1889 as part of Cambridge's growth into a major administrative center during the late 1800s. The design reflected popular architectural trends of that period, establishing the building as a landmark in the city's development.

The building serves as a central element of both the City Hall Historic District and the Central Square Historic District.

The building houses municipal offices and administrative services that operate during standard business hours on weekdays. Visitors should plan their visit accordingly, as most departments are available during daytime hours rather than evenings or weekends.

On May 17, 2004, this location issued the first legal marriage licenses to same-sex couples anywhere in the United States. This milestone marked Cambridge as a place where significant social change took place.
