Tårnborg Castle was a royal medieval castle. It consisted of a central tower of 8m x 8m, surrounded by a square outer wall. An excavation in the castle courtyard in 1894 also revealed the remains of three small houses. The castle stood from about 1231 up to the last part of the 14th century when a new castle in Korsør took over Tårnborg's role. From written sources we know that the castle was captured several times, once in 1326 when King Christopher II’s son was forced to submit to the rebellious troops after a two-week siege.

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.
