Fort Fleur d'Épée, Fort in Le Gosier, Guadeloupe, France.

Fort Fleur d'Épée is a fortified structure on the island of Le Gosier featuring underground chambers and passages that run through the complex. The layout reflects classical European military architecture designed for defensive purposes.

The fort was built between 1750 and 1763 and became a flashpoint during conflicts between French and British forces. Control shifted multiple times until 1794, when Victor Hugues led a military operation that reclaimed it for France.

The fort is part of the "Route de l'Esclave/Traces-Mémoires en Guadeloupe" circuit, linked to UNESCO's Routes of Enslaved Peoples. Its wide corridors host occasional exhibitions of Creole art, and a 2003 inventory recorded over 200 engravings, from 1812 to 2002, including writings and drawings of ships.

The fort stands on the top of Morne Fleur d'Épée above Le Gosier, reached by road; the entrance crosses a fixed stone bridge over the ditch dug in the 1830s, flanked by two masonry pillars. Paths and underground passages have uneven floors, so wear sturdy shoes. The site is exposed on the hilltop.

More than 200 graffiti marks, dated between 1812 and 2002, were inventoried inside the fort by the end of 2003; they include inscriptions and drawings of ships. The fort is also part of the "Route de l'Esclave/Traces-Mémoires en Guadeloupe" circuit linked to UNESCO's Routes of Enslaved Peoples.
