Château Laroche, also known as the Loveland Castle, is a museum on the banks of the Little Miami River north of Loveland, Ohio, United States. Built in the style of a Medieval castle, construction began in 1927 by Boy Scout troop leader, World War I veteran, and medievalist Harry D. Andrews. He built the castle on promotional plots of land that were obtained by paying for one-year subscriptions to The Cincinnati Enquirer. Andrews named his castle after a military hospital in the Château de la Roche in southwest France, where he was stationed during the First World War. Its name means "Rock Castle" in French.
