Le Trépied is a prehistoric passage grave built during the Neolithic period (4000 to 2500 BC). It is a single chamber tomb, 5.5 metres in length and two metres at its widest point with three capstones, one of which was returned to its original position in the 1870s after it had fallen off.
Excavations in 1840 discovered pottery and flint arrowheads dating to 1800BC showing that the site was still in use then. The tomb was repeatedly mentioned in the 17th century witch trials as a meeting place for witches and as the venue for the sabbats. One story says that the witches used to perform chants mocking the Virgin Mary whose shrine of Notre Dame de Lihou once stood on the nearby island which can be seen from the headland where the tomb stands.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
