Fastighetsvärn K57 (Kg)

Fastighetsvärn K57 (Kg) is a Swedish military bunker located near Karlskrona, a city with a rich history of coastal defense. Karlskrona, founded in 1680, has long served as a strategic naval base for Sweden, and its extensive network of underground fortifications reflects this military heritage. The bunker is part of Sweden's broader system of civil and military preparedness, which includes thousands of square meters of hidden underground facilities designed to protect critical infrastructure and personnel during times of heightened threat.
