The first written record of Egholm estate dates back to 1405, but the oldest building (today a magazine) dates from the 1200s. It was probably a keep built to the highest part. The current neo-classical main building was constructed in 1841 by Wolfgang von Haffner. Today Egholm is a museum.
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.
