Drawing by Claude-Louis Bernier, 1786. The Chapelle de Villeroy was placed along the western wall, i.e. at the opposite end from the church. The perspective is faulty, one of the crosses seems to block the entrance door to the chapel, while Bernier's own plan drawing shows that there was at least the space of two arcades between the cross and the door. There's a larger version here: Villeroy.
