Austrått Fort is a disused coastal artillery site constructed in 1942 by the German Wehrmacht to protect the Trondheimsfjord during the German occupation of Norway during World War II. The fort's centrepiece is a triple 28 cm SK C/34 naval gun turret from the German battleship Gneisenau, which was damaged in Kiel. The three gun turret weighs 800 tonnes and was capable of firing 38 kilometres. The last firing took place in 1953 and the fort was decommissioned in 1968. It opened as a museum in 1991.

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.
