The Château du Bernstein is a ruined castle in Dambach-la-Ville. It is among the oldest in Alsace. It was first mentioned at the beginning of the 11th century, though the northern surrounding wall can be dated to prehistoric times. The upper castle with keep, manor house and advanced works probably dates from the end of the 12th and early 13th centuries. In the Gothic era, the manor house was separated from the keep by a ditch, transformed later into a cistern. Towards the end of the 15th century, the St. Marguerite tower, so called from the name of the chapel there, was built in the rear courtyard.
Around 1835, Félix Dartein cleared the ground of the lower castle to build a house and some outbuildings which have disappeared.
Originally, the castle belonged to the Counts of Eguisheim Dabo. After the siege of 1227, it became the property of the bishop of Strasbourg and seat of the episcopal bailiffs until 1580.
The Château du Bernstein is state property and has been listed as a monument historique by the French Ministry of Culture since 1931.

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.
