Popularly called the Presbytery, but actually a rectory (it is a detached house). Like the church, the rectory has a checkerboard pattern (although simplified in scale with the building) made with white Caen stone and dark flint for the first story. The second story is wood and stucco, half-timbered. The facade has been a listed monument since 1910. It has Renaissance style medallions in a frieze and a stone gargoyle (waterspout) in the shape of a "Manneken" that predates the famous one of Brussels. In 1650 the building was acquired by the city; in 1883 it was restored.
