In 1939, at the request of Hitler and the annexation of Klaipėda region to Germany, it was decided to build artillery batteries on the shores of the Baltic Sea. The first "Memel Sud" ("Klaipeda-South") was to appear in Smiltyne, the second - "Memel Nord" ("Klaipeda-North") - outside Giruliai, in the village of Kukuliskiai. Only the latter, also called the Karklė battery, has been completed.
Although raised according to typical German naval bunker models, these buildings are unique. Interestingly, the primary function of the battery was anti-ship - to protect the coast from the sea side. Still, the battery was converted to an anti-aircraft. At one time, half a hundred soldiers were on duty here, and their base was nearby - in the territory of the current "Žuvėdra" camp. The battery operated even after the war, even until 1955, when border guards settled here intermittently.
During military operations, the battery is almost undamaged. The complex of military fortifications consists of three buildings, the largest of which has an area of 500 sq. M. m, the second - 240 sq. m. m. The smallest facility closest to the sea - 140 sq. M. m area. In the center of the battery is a fire control post of a concrete structure, on both sides of it - two artillery blocks of a concrete structure, with cannon platforms and ammunition storages at each end and the crew quarters between them. Equipped and caseminated power plant bunker, which provided electricity to battery floodlights.
2002 one artillery block was partially arranged, and an exposition about the Seaside Regional Park was installed there. Since 2009 Klaipeda Military History Club together with the regional park has started to create an exposition about these and other defensive fortifications. For example, in 2009 an extremely rare FLAK-40 cannon tube was unearthed - only three in the world: in Germany, the USA and here at the seaside. The projectiles of these cannons were able to fly 17 km, and one of the planes fired from this place was shot down by an aircraft and is now lying on the bottom of the Baltic.
