A military bunker complex located near Karlskrona in Blekinge County, southern Sweden. The site is identified by the Swedish military designation 'Värn 1138:1' and the colloquial name 'Kg-hatt'. The coordinates place it within a region historically significant for Sweden's coastal defense and naval infrastructure, particularly around the Baltic Sea.
During the Cold War, Sweden maintained an extensive network of coastal artillery fortifications to protect its shores and strategic ports like Karlskrona, the country's primary naval base. Structures of this type were typically part of the 'Kustartilleriet' (Coastal Artillery) and designed for long-range surveillance and fire control. While specific documentation for this exact bunker is not available in the provided sources, its designation and location strongly suggest it served a defensive role within this system.
The current physical state and exact function of the Värn 1138:1 bunker are unconfirmed by the available historical records. Such sites often remain as concrete relics on the coastline, sometimes repurposed or abandoned. Further local archival research or on-site investigation would be required to determine its precise construction date, armament, and operational history.
