The citadel of Corte is the only fortification that is inside Corsica. It is at the top of a hill, in the highest part of the city, and is triangular. It is in excellent condition and was built in 1419, although some parts of the exterior were added in the nineteenth century. The highest part of the citadel is a tower called Eagle's Nest and from it you can see stunning views of the Corsican mountains, the Tavignano and Restonica rivers and the city of Corte. In the center of the citadel are two buildings, the Caserne Serrurier and Caserne Padua. The Caserne Serrurier houses the Corsica Museum, a pretty curoius museum with numerous articles that are typical of the island, the most numerous are the objects of craftsmanship.
