The neo-Gothic church was built before 1597 and replaced another building from the 11th century, which stood near the current chapel of Notre-Dame des Affligés. It was partially rebuilt in 1855. The tower dates from 1683. The originality of this construction lies in the fact that the bell tower is not above the entrance door, but above the choir. The door is simply formed by a pointed arch decorated with a pentacle. The first two bays of the nave are built of red brick and the last two in chalk. The four bays of the nave also have a pointed arch. The bell tower is formed by a gable wall that projects above the nave. The buttresses on this side are placed in line with the wall, creating a flat surface. The buttresses of the bell tower on the choir side are well placed on the corners
