Gräfsnäs Castle today consists of a heavily restored main building with barred windows and surrounding dry moat. The ruins are remnants of the original palatial fortress built in Swedish-French Renaissance style. The castle, which met with such a tragic fate, was constructed in c. 1571 and belonged to many different owners (like Leijonhufvud, Sparre and Holstein-Augustenburg families) before it was finally abandoned in the late 19th century. The tragic coincidence was that Gräfsnäs was damaged by fire in every one hundred years (1634, 1734 and 1834).
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.
