Asserbo Castle was founded by Bishop Absalon in the 1100s as a monastery for monks of the Carthusian Order. The castle was taken over first by the King around 1560 and in subsequent centuries by drifting sand. The castle was liberated from the sand in two phases: initially by King Frederik VII in 1849 and then by National Museum excavations in 1972.
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.
