The Citadelle Laferrière or, Citadelle Henri Christophe, or simply the Citadelle (), is a large early 19th-century fortress situated on the Bonnet à l'Evêque mountaintop in Nord, Haiti. The imposing structure is located approximately south of the city of Cap-Haïtien, southwest of the Three Bays Protected Area, and uphill from the town of Milot. Commissioned by Haitian revolutionary Henri Christophe, and built by tens of thousands of former slaves, the Citadelle was the linchpin of the newly independent Haiti's defensive strategy against potential French incursion.
