Žumberk Castle was probably built during the end of the 13th century, on a hilltop above the village, and was known under the German name Sunenberg. Its walls formed a pentagon and were surrounded by a deep moat, with a service yard was placed next to the castle. Later, a township grew up under the hill.
The first known owner of the castle and neighbouring villages was a robber knight; ownership of the castle changed many times afterwards. At the beginning of the 18th century, the castle was not inhabited, though during 1760–70 a physician lived there. The castle became desolate and was left to be a source of construction material.
During 1926–48 the castle was owned by the Club of Czech Tourists, and its structure was stabilized to prevent further destruction. Today the market town of Žumberk is responsible for its maintenance, and access to the castle is unlimited and free.

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.
