Värn 1820a, also known as Kg III, is a military bunker located near the coast of southern Sweden. It was part of the country's coastal defense system during World War II and the Cold War era. The bunker's designation 'Kg III' indicates it was a type of fortified position used for coastal artillery support and defense against potential invasions from the sea.
Today, the structure stands as a reminder of Sweden's military history and its efforts to protect its coastline during times of global conflict.
