Seneca’s City Hall was built on the site of a wooden firehouse and was completed in 1916 in the Beaux Arts style. It housed all city and county offices as well as the town library and the police and fire departments. Built for $20,000 with pre-cast concrete columns and brick and tile made in the Seneca Brick Works, it was intended to centralize city services, but that arrangement soon proved unsuccessful as the prosperous town’s departments quickly outgrew their space. The fire department later moved across the street to a modern firehouse as new fire trucks were needed, county offices moved north to a new building, and the library relocated to the renovated and enlarged Old Stone Church on the opposite corner. During World War II, City Hall served as an assembly center for women making first aid kits for the Red Cross and as a collection point for scrap materials for the war effort. Today the mayor presides over City Council meetings there, the daily noon siren sounds from the roof, a museum with Seneca’s antique Stutz fire truck occupies the firehouse space on the building’s west side, and colored lights outline the building for holidays and parades.
