Built in the style of a Medieval castle, construction began in the 1927 by Boy Scout troop leader, World War I veteran, and medievalist Harry D.

[1] He built the castle on promotional plots of land that were obtained by paying for one-year subscriptions to The Cincinnati Enquirer.

[1] 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.

He pulled stones from the nearby Little Miami River, and when that supply was exhausted, molded bricks with cement and quart milk cartons.

The walls of the upstairs chapel feature many stones brought back by Andrews in his world travels and others sent to him from foreign locations by his friends and followers.
