My friend Jen and I went to Ha Ha Tonka castle yesterday. www.mostateparks.com/park/ha-ha-tonka-state-park We had a great time exploring the castle ruins and taking photos. This castle was completed in the 1920's, but burned down in 1942. The state of Missouri purchased it and turned it into a State Park. The water tower didn't burn down in 1942, but it did get burned by vandals in 1976.
