Chateau de Caen, also known as the Caen Castle, is one of the largest medieval fortresses in all of Europe. The castle was built in the 11th century by William the Conqueror, the King of England and the Duke of Normandy.
For the most part of its long history, the chateau has been the major seat of power in the Normandy region and during the Hundred Year's War, it was a major English stronghold. Today, the chateau is an important part of Caen's heritage and houses the Museum of Fine Arts and the Normandy Museum.
Once inside the castle, you can get spectacular views of the castle surroundings as well as of the city of Caen from above the large moat of the fortress.
