Église priorale Sainte-Opportune de Moussy-le-Neuf

The Église priorale Sainte-Opportune is a ruined church in Moussy-le-Neuf in Seine-et-Marne where the choir wall and lower sections of the northern side still stand visible among vegetation. The remains now form part of the adjoining farm complex where agricultural buildings occupy the surrounding area.

This priory church was founded in 1220 and initially housed the relics of Saint Opportune, making it an important religious center. The relics were transferred to Notre-Dame Cathedral in Paris during the medieval period, an event that significantly reduced the site's prominence.

The building was dedicated to Saint Opportune and served as a pilgrimage destination during the medieval period. The engraved tombstones with Gothic lettering visible in the ruins mark the resting places of those who served here.

The ruins sit on private farmland along Rue Jeanne d'Arc and are partly visible from the road without entering the property. Getting closer to examine the structure requires permission from the property owners, so respect the private boundaries.

Beneath the visible ruins lies a vault or crypt from the 10th century that preserves portions of the original church structure. These underground spaces offer a hidden layer of history that visitors often miss when viewing the site from above ground.
