Jever castle dates back to a weir from the late 14th century. The fortress got its typical characteristics mostly from the massive keep, which during the 15th and 16th century was surrounded by a Vierseitanlage. When Jever became part of the Duchy of Oldenburg in 1818, the castle was declared an auxiliary residence of the Dukes of Oldenburg and the now useless outbuildings and fortification were done away with. The museum has been situated in the castle since 1921 and features collections of cultural history, folklore and the archaeology of the Jever region.
The historic rooms also give an overview of the lifestyle of the 16th to 19th century. You will have the best view from the 67 meter-high castle tower. The viewing platform offers a unique view over the expanse of the Friesian coast.

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.
