The Romanesque church of Notre-Dame-de-l'Assomption in Moustiers-Sainte-Marie was built in the 12th century. It is located in the heart of the village on the site of a monastery founded in the 5th century by monks from the Lérins abbey. Its Romanesque nave - onto which three semicircular vaulted chapels open - is divided into five spans. In 1336, Pierre de Pratis, the commendatory prior, ordered the expansion of the church, its choir was then rebuilt in Gothic style without respecting the axis of the nave from which it is offset.
