In 1100, a nobleman named Heinrich named himself after the old Clingenburg (castle). He belonged to the noble family of Reginbodo. The Clingengurg castle was built around 1160-1170 by Conradus Colbo, who was cup-bearer to Emperor Friedrich Barbarossa.
About 1250, the Bickenbach noble family moved into the castle; the Bickenbachs later held many influential offices in the Holy Roman Empire and many a time turned up in Imperial politics as brokers.
After the Bickenbachs died out in 1500, the town, castle and lordly domain passed to the Archbishop of Mainz. Clingenburg castle was destroyed by the French in the late 17th century and never rebuilt. It remained a ruin.
In the 20th century Clingenburg was opened up to tourism with a restaurant and a lookout platform affording visitors a view over the old town and the Main valley. Since 1994, the Clingenburg-Festspiele have been taking place, drawing many visitors each year with changing plays and musicals.
The Château du Lude is one of the many great châteaux of the Loire Valley in France. 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.
