After the war the Grønsvik Coastal Fort, as with many other coastal fortresses, was badly damaged. Today Grønsvik has been partially restored and transformed into a museum featuring exhibitions about the war in general and the coastal fortifications in particular. The bunkers, mountain halls, gun emplacements and defence positions are now open to the public year-round. The museum is located in Grønsvika on road no. 17 (the Coastal Route) just north of Stokkvågen.
