Park Square Historic District (Pittsfield, Massachusetts)

The Park Square Historic District is a historic district in Pittsfield, Massachusetts. The district is centered on the historic heart of Pittsfield encompassing a number city blocks adjacent to Park Square, which is at the junction of North, South, East, and West Streets.

When first listed on the National Register of Historic Places in 1975, the district encompassed the park and eight buildings that faced it, including the Old Town Hall, the county courthouse, the Berkshire Athaneum, and the First Church of Christ. In December 1991, the boundaries were expanded to the area roughly bounded by East Housatonic, South, North and Fenn Streets, and Wendell Avenue, adding 39 buildings to the district. Notable buildings included in this extension include the present City Hall (a repurposed post office building), the Berkshire Life Insurance Company Building, the Allen Hotel, the Berkshire Museum of Art and Natural History, and the Masonic temple.
