Montclair castle was built by Arnulf von Walecourt in the late 12th century. The site was a fief from Trier archbishop. The castle was built to the site of old Frankish castle. In 1351 the castle was conquered and razed by the troops of Archbishop Baldwin of Luxembourg. Jakob von Sierck built the new castle in 1434-1439. It fell into disrepair and started to decay in the 17th century. Montclair was restored in 1992-1993.

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.
