MKB 5/503 Nordberg is a former German coastal artillery battery located in Norway, constructed during World War II as part of the Atlantic Wall defenses. The site was built to protect the strategic coastline and control maritime access in the region. These batteries formed part of the broader German military infrastructure along the Norwegian coast, designed to defend against potential Allied naval incursions.
The concrete fortifications and gun emplacements remain as historical remnants of the wartime occupation period.
