Fort Delgrès is a 17th-century fortification on a promontory overlooking the harbour of Basse-Terre, built by the French in 1649 and substantially expanded through the colonial period. It is named after Louis Delgrès, a hero of Guadeloupe's resistance to the reimposition of slavery in 1802 — one of the most dramatic episodes in the history of the French Caribbean.
The fort today is a national monument and houses an exhibition on its history and on Delgrès and his companions. The fortifications themselves are impressive, with thick stone walls, gun platforms overlooking the sea, and the original gates and towers largely intact. From the ramparts there are views across to the harbour and Basse-Terre's old town. Entry is free and the site is open daily. The stone circle memorial to the 1802 uprising is on the flanks of the hill below the fort.
