Vecdole Castle (Schloss Alt-Dahlen) was built in the early 13th century (before 1226 when it was first time mentioned). It was built as a vassal castle for the arcbishop of Riga and destroyed already in 1298. Today only ruins remain.
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.
