Oscarsborg Fortress
Oscarsborg Fortress is a coastal fortification in the Oslofjord near Drøbak, Norway, sited mainly on the small islets Nordre Kaholmen and Søndre Kaholmen and supported by batteries on the island Håøya and on the mainland. It is best known for engaging and sinking the German cruiser Blücher on 9 April 1940. The site is now a publicly accessible museum and resort and is a protected cultural monument.

As it stood in 1940
What Oscarsborg Fortress looked like in its prime.
Low rocky islets densely treed with clusters of low concrete and stone military emplacements: squat concrete gun emplacements and casemates, small bunker blocks, and timber service buildings beside a narrow stone quay. Dark, heavy gun barrels project from reinforced concrete platforms; the shoreline has simple wooden boathouses and timber docks. The fjord narrows on either side with wooded hills and scattered houses; the overall scale is compact and maritime, with signs of recent maintenance at the battery positions.
