The French fort on Sainte-Marie Island (Nosy Boraha) is one of the oldest colonial structures in Madagascar, witnessing France's early ambitions in the Indian Ocean. It was constructed in the mid-18th century, around 1750, on a hill overlooking the bay of Ambodifotatra after the island was officially ceded to France. The fort served as a military base to secure the island against pirates, who had long used Sainte-Marie as a haven, and to monitor maritime trade routes. The architecture is characterized by massive stone walls and bastions, typical of European fortification design of the era. Nearby stands Madagascar's oldest stone church, consecrated in 1857, which is deeply intertwined with the island's missionary history. Despite the harsh tropical environment, parts of the fortifications and original cannons remain preserved today. The fort stands as a symbol of the inception of permanent French presence in the region and provides profound insight into colonial military history and the island's strategic significance.
