Brahehus Castle was built by Per Brahe between 1637 and 1650s. Soon after Per Brahe died in 1680 Brahehus was abandoned and moved as a Crown property in the Great Reduction under Charles XI of Sweden. In 1708 the castle was destroyed by fire and not rebuilt anymore. From the ruins you have a fantastic view of lakes Vättern and Visingsö.
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.
