Catholic building located in the heart of the city of Aire-sur-la-Lys, in Pas-de-Calais, the Saint-Pierre collegiate church was built between the end of the 15th century and the middle of the 16th century, and today benefits from a classification in the Historical monuments.
Originally the Chapter Church of Saint-Pierre d'Aire, it was built on the remains of a first Romanesque church from the 12th century, of which there are still some vestiges, in particular on the bases of the pillars of the apse. Ruined during the siege of 1710 and then by the bombings of the Second World War, it has undergone several successive reconstruction campaigns, while retaining its original plan.
Considered one of the most important monuments of flamboyant and Renaissance style in the southern Netherlands, the Collegiate Church of Saint-Pierre impresses with its majestic dimensions as well as with its compact overall plan and its few remains of furniture of origin as a statue of Notre-Dame Panetière from the 16th century and a statue of the Flemish Virgin from the end of the 15th century.
