Classified as a historic monument in 1913, come and discover this place which retraces more than 1000 years of history and which is among the greatest examples of Gothic art. Indeed, if the choir of the building dates from the late twelfth century, at a time when the city of Montreuil was very appreciated by the kings of France, several constructions and reconstructions have enamelled its history over the centuries. Today, the important restoration works already carried out in the past are being continued.
