The massive stonewall, stretching straightforward between the two coasts of Öland, was built due the orders of Duke Karl Gustav, later King Karl X Gustav in 1653. The intention was to keep the deer in the royal hunting grounds from escaping them, although many speculate it served the double purpose of keeping the peasantry away from his sport. It was built with local materials and local labour in lieu of taxes. The surrealistic wall in open landscape is still in good condition.
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.
