 The most palatial were the Chateau St. Louis in Quebec city, the Government building in Cap-Francois, the Governor's mansion in Cayenne, and the church (now cathedral) in Cap-Haitien (now Our Lady of the Assumption Cathedral, Cap-Haïtien).The French also built extensive structures in Louisiana, especially in New Orleans and plantation country Destrehan Plantation, although very little survives today from the French period.Nevertheless, French-style buildings were built there for a long time, as they were in post-colonial Haiti, notably the Sans-Souci Palace of King Henry Christophe.
