One of six island fortifications of its kind, the Citadelle, a Vauban-style fortress (1769–78), is built around the original 15th-century bastion at the highest point of the cliff, with the river below. In 1769, after the defeat of Ponte Novu, Corsica came under French rule. Count de Vaux, who held Corte, undertook the construction of the citadel's second reconstruction to strengthen the defense system of the city. The building contains the Musée de la Corse
(Corsica Museum), dedicated to the island's history and ethnography.
