The Church of Saint-Étienne of Le Marin was built in 1766 using cut stone. It stands out from the island's other churches thanks to its bell tower, located right next to the building. Its architecture is in the Jesuit style.
The interior of the church is just as surprising as the exterior. The framework resembles the hull of an overturned boat. In the choir is a magnificent white marble altar which, according to legend, was intended for the cathedral in Lima, Peru, but was shipwrecked not far from the coast of Le Marin.
It was donated by François Cornet, a wealthy resident of the town, thanks to a bequest of 6,000 pounds in 1769. He had already donated the statues of the Virgin Mary, the Child Jesus, and Saint Stephen to the church.
