Stegeholm's Castle Ruin is located on Slottsholmen by the mouth of Gamlebyviken. The oldest notes about Stegeholms castle are from the 14th century. It was probably built before 1370 by Albert II, Duke of Mecklenburg (the father of King Albert of Sweden). The castle was destroyed by fire in 1517 and rebuilt in 1521. In 1612 it was conquered by Danish. The final destruction appeared in 1677 when Stegeholm was destroyed by Danish-Dutch fleet. Today Västerviks Visfestival (Song festival) is organized in the castle ruins annually.
References: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.
