This church is a jewel of Gothic architecture of the Ile-de-France. The work lasted a little over three centuries, from the late twelfth century to the early sixteenth century. The dimensions of the building are impressive: total interior length (including the ruined nave): 57 m, length of the transept: 29 m, height of the vaults: 18 m, height of the tower 50 m.
