"The Old State Capitol building is a striking Gothic-Revival castle that was built in 1847. It is noteworthy both from a historical and architectural perspective, and is worth a look, even if just from the outside. The castle was burned by the Union Army, and in 1882, it was repaired and served as the state capitol until 1932, when the new State Capitol building opened."
