1. Berkshire County Courthouse, 76 East Street In 1868, Pittsfield replaced Lenox as the county seat, setting the stage for the construction of the Berkshire County Courthouse. Completed in 1871, the building was constructed from marble taken from a quarry nearby in Stockbridge. The property on which the Court House is located was the site of the Peace Party house, owned by John Chandler Williams, the donor of Park Square. Architect Louis Weissbein of Boston gave the Courthouse its unique design by adding Italianate detailing: a large fan window with a keystone above a pavilion, columns at the front entrance, round-top windows, and marble medallions. The Berkshire County Courthouse was renamed the Silvio O. Conte Courthouse on September 27, 1992. Conte (1921-1991) was an influential figure in the U.S. Congress. The entire Berkshire County Court complex is named after Francis Joseph Quirico (1911-1999), who was a justice on the state Supreme Judicial Court.
