Eberbach Castle consists of three separate castles situated about 160 metres high above the river Neckar. It is assumed that the front castle was built in the last quarter of the 12th century, the middle castle ca. 1200 and the rear castle in the second quarter of the 13th century. In 1227 King Henry VII was given Eberbach Castle as a fief by the Bishop of Worms. Presumably the castles remained in the possession of the empire until 1330. After that, the castles were pledged to the palsgraves who subsequently used them as a bailiwick of the Electoral Palatinate.
In 1402 Ruprecht III of the Palatinate pledged the town and the castles to the knight Hans von Hirschhorn. In 1403 he obtained permission from the king to demolish and raze the castle, since presumably it was not of any use, but only entailed costs. He thus got rid of competitors for his castles in Hirschhorn and Zwingenberg. By and by the ruins were dismantled and their stones used for building projects in Eberbach, in particular for building walls to fend off game in order to protect the fields lying next to the woodland. Excavations in 1908-09 and 1927-28 exposed the remains of the front and middle castles, and some parts were reconstructed. From 1959-1963 systematic scientific research was carried out, and the rear castle was reconstructed in parts.

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.
