Noticed in today's real estate listings...

A medieval castle once ruled by Charlemagne, the “King of the Franks,” is for sale in Italy, dungeon included.

Located (exactly) on the border of Tuscany and Umbria, the castle dates to 802...

Features include restored stone battlements with gun ports, four turrets, a moat and the dungeon, an add-on amenity reportedly built in 1500. Five buildings are clustered around the circular courtyard and the property includes about 32 acres of olive groves and woodlands.

There are photos too.

Well at last. I've been looking for a house with those features for the longest time.
