Pitsligo Castle originated as a 15th-century keep. There is an arched gateway in the west wall of the outer court, with the date 1656 and the arms of the Forbes and Erskines. In the inner court the date is shown as 1663. At the north-east angle of the courtyard there is a tall flanking drum-tower. The main tower had three vaulted stories, but almost all above the lowest has disappeared. There is a stair tower at the north-east corner which is better preserved. There are panels dated 1577 over the courtyard doorway.

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.
