Fjell fortress was built by the German occupation forces during the Second World War. The construction works were commenced late summer 1942, and completed so far that they could fire the main gun for the first time as early as in June–July 1943. The fort was a significant link in the coastal defence of Norway.
The main gun was also to a certain extent employed in the interception of foreign aircraft raids against Bergen.The fortress has areas over and under the ground, with a network of tunnels two miles long on the surface and in the mountains.
The fortress area is today the property of the Norwegian Armed Forces, while Sotra og Øygarden Forsvarsforening (Sotra and Øygarden Defence Association) are responsible for conducting the preservation and maintenance.

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.
