This sanctuary was already frequented in the Middle Ages. Forty or fifty years ago, locals still remember the pilgrimages organized to Osmoy. The small chapel was restored around 1970. It was the site of a pilgrimage where the faithful came from far and wide to venerate the statue of Our Lady, a polychrome wooden statue from the 15th century.

Built at the end of the 12th century by the Counts of Montfort and listed as a Historic Monument since 1889, the Houdan Tower was used to watch for enemies and defend the territory. The Keep consists of a 15 m diameter and 21 m high tower, flanked by four turrets of the same height located at the four cardinal points. From the 16th century until the French Revolution, the Keep served as a prison, and executions took place at the foot of the Tower. The first water reservoir was installed in the tower in 1880. The second, built in 1952, is still visible. Tours are available on certain days.
