Šomoška Castle is unique among the Slovak castles as it is built of unconventional hexagonal basalt pillars. It was probably built in the later half of the 13th century after the Tartar invasion. After suppression of the Rákoczis rebellion, the Emperor had pulled down several castles, but Šomoška was spared. However, it gradually decayed and the last tower burnt in 1826 when a lighting struck it. In 1972 extensive conservation and partial reconstruction saved the castle before its total destruction.

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.
