Château Laroche, also known as the Loveland Castle, is a museum on the banks of the Little Miami River in Loveland, Ohio, United States. A folly of a historical European castle, construction began in 1929 by Boy Scout troop leader, World War I veteran, and medievalist Harry D. Andrews. He built the castle on two free plots of land that his scouts obtained by paying for one-year subscriptions to The Cincinnati Enquirer. Andrews named his castle after a military hospital in the Chateau La Roche in southwest France where he was stationed during the First World War.
