The 15.2 cm battery at Landsort

The 15.2 cm battery at Landsort was the first installation built as part of the Havsbandslinjen. The batteries were designed to support the fleet's operations and protect Stockholm and eastern Mellansverige. Located on the southern tip of Öja, Landsort's battery consisted of three gun positions, each with its own 15.2 cm gun in an armored turret. The construction began in November 1933 and was completed five years later, with additions continuing throughout the second world war.

The battery was equipped with three guns from the 12th battery at Rindö to save time, as their measurements were already known. These guns were taken from Rindö in November 1933, and the transport to Landsort began in April of the following year. Two armored turrets for observation positions were also taken from Myttingefortet and Vretafortet.

The battery was in use from 1938 until the end of the 1960s. It was manned during the readiness period from 1939 to 1945. In the 1970s, the battery was replaced by the ERSTA battery on northern Öja. Today, gun number 2 remains complete while guns 1 and 3 are preserved to their outer parts, including the gun cupolas and barrels.
