The Sans-Souci Palace is a palace in Haiti in the town of Milot, Nord, located approximately 5 kilometres (3.1 mi) northeast of the Citadelle Laferrière, and 13 kilometres (8.1 mi) southwest of the Three Bays Protected Area.
It was the royal residence of King Henri I (better known as Henri Christophe) of Haiti, Queen Marie-Louise and their two daughters. It was the most important of nine palaces built by the king, as well as fifteen châteaux, numerous forts, and sprawling summer homes on his twenty plantations. Construction of the palace started in 1810 and was completed in 1813. Its name translated from French means "carefree". The nearest airport and large city is Cap-Haïtien.
