The Château du Landsberg in Heiligenstein includes a Zwinger with two sets of defensive walls. The central part of the castle was built in the late 12th century, and the newer outer castle added onto at the start of the 13th century by Conrad de Landsberg to provide defence for the abbeys of Mont Sainte-Odile, Niedermunster, Truttenhausen and Andlau. More recent additions were made in the 15th century. Herrad of Landsberg was born here around 1130. The castle is privately owned.

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.
