Hünenberg Castle was built in the 12th century and mentioned first time in 1173. At the Battle of Sempach in 1386 Hünenberg fought on the side of Habsburg family and the castle was destroyed after the defeat. During the following three decades the Hünenberg family also lost their power and reputation. In 1416, Rudolf von Hünenberg sold the ruined castle and its rights to the Bütler brothers. The keep was still standing into the 19th century.
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.
