The monumental Thun Castle was built in the mid-13th century, but the current appearance dates mainly from the 16th and 17th centuries. The Spanish style gate built in 1566 in Moorish style, probably after Giorgio Thun was visited in Spain. The most famous room is the seventeenth-century Bishop's Room, entirely covered of pine wood, with a coffered ceiling and a tiled stove.
Today Thun castle is open to the public.
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.
