Command post of an anti-aircraft battery

At the top of the hill, reaching a height of 84.4 meters above the surrounding area, during World War II, the Germans built an anti-aircraft defense position. It was one of the larger units of this type in Pomerania in terms of the number of guns. In the immediate vicinity, there were two earth bunkers for ammunition. In the nearby Spółdzielcza Street, two wooden barracks and two concrete buildings have been preserved, which were once part of the battery barracks. The battery was located in a convenient terrain, enabling the defense of both Gdańsk and the southern districts of Gdynia. In case of hostile ships appearing in the Gdańsk Bay, it was possible to directly shell them from this position. Additionally, the battery played a significant role in protecting the port of Gdynia from air raids from the south. The rangefinder position was built according to a similar plan as the firing battery in Łężycach, however, in Kolibki, it was preserved in a much better condition because it was not involved in direct frontline combat like in Łężycach.
