Bunkers in Antakalnis, Military bunker complex in Antakalnis district, Lithuania.
The Antakalnis bunkers comprise five ammunition storage structures built from reinforced concrete with ten separate entrances and multiple underground connecting passages. The complex sits within the Sapieginė hills near Šilo Street, surrounded by the forested slopes of Pavilniai Regional Park.
Construction took place between 1924 and 1926 when the region was under Polish control and Vilnius required defensive fortifications. The project was part of a broader strategy to strengthen the city's security during that period.
The complex takes its name from the Antakalnis neighborhood where it stands and was registered as a cultural monument for its engineering methods. When you walk through, you can observe how the thick concrete walls and underground passages show the building techniques used in that era.
The site is surrounded by forest, so sturdy footwear and weather-appropriate clothing are recommended for your visit. The Sapieginė hills can be slippery, especially after rain, so careful footing is important.
The underground chambers provide shelter for thousands of bats, particularly European broad-eared species. This makes the complex an important nature refuge where visitors encounter a functioning ecosystem within the bunker system.
