Construction of the Catholic church "Notre Dame de l'Assomption" took five years and was completed in 1829. The Spanish-influenced style is quite unusual for a religious building in the French West Indies.
A meticulous restoration in 2006 restored the church to its original beauty. Next door is a building that once housed the parish hall. Ceded to the Collectivité by the bishopric, it is now the Théâtre du Paradis, which hosts shows and artistic activities.
On the other side of the street, a funeral chapel has been built in honor of Sister Armelle, who died in 1947, and a rotunda for the Sacré Coeur in honor of the sailors of Saint-Barthélemy.
On the slope behind the church are the presbytery and the bell tower. The latter is built separately, on the hillside, to avoid damage to the church in the event of the bells falling during a cyclone, but also so that they can be heard from all over the town.
