Washington Hall in Central City is the oldest continually used public building in the state. The original Gilpin County courthouse and jail, it was built of hand-hewn square logs in 1862 (some of which are still visible in the staircase leading to the Art Gallery on the second floor). Washington Hall, a National Historic Site, is currently home to the the Gilpin Historical Society's Tour Office and the Gilpin County Arts Association's gallery.
