Fort Napoléon is located on Terre-de-Haut Island, in the Îles des Saintes, Guadeloupe. Built on the morne called Mire, it was originally named Fort Louis. It was destroyed by British forces in 1809. It was rebuilt in 1867, and named after Napoleon III, but never saw use in battle, and was instead used as a penitentiary. It has now been turned into a museum dedicated to the Saintes’ history, culture, and environment. It also has contains the Jardin exotique du Fort Napoléon, a botanical garden dedicated to local succulent plants and iguanas.
Additionally, there is a myth that the fort is haunted by the spirit of a young French girl who fell in love with a British officer. Her lover promised to return for her when his duty was up, however after waiting for several years the young woman lost hope.
