640-Year-Old Castle and Moat Uncovered Under a French Hotel

A 640-year-old castle was found underneath a French hotel. Archaeologists said they knew the ruins of this castle existed somewhere but didn’t have the details until construction started on a new museum. Château de l'Hermine in Vannes, France, was built in the 1380s. It was created to be a fortress for Jean IV, then-Duke of Brittany. The Chateau was not fully destroyed, merely built over. When archaeologists began excavating, they found walls, staircases, and even a moat that were intact.
