The facility was designed to allow high-ranking military officials to command naval operations from complete subterranean isolation.
The bunkers were built using reinforced concrete and earth shielding to mask the facility from aerial reconnaissance.
The tunnel network links several distinct bunkers that functioned as independent modules for communication, command, and support.
During the Cold War, the site remained largely unknown to the general public, including many local residents of Świnoujście.
Authentic period items, including radio transmitters and gas masks, are displayed exactly where they were used.
The name 'Vineta' is derived from a legendary lost city said to be submerged in the Baltic Sea.
The complex includes heavy armored blast doors designed to seal off sections of the facility in the event of an atmospheric breach.
The Underground City in Świnoujście is a former German coastal battery, known as Vineta, transformed during the Cold War into a secret command center for the Polish People's Army. The complex consists of several bunkers interconnected by a kilometer-long underground tunnel system hidden beneath the dunes. It served as a strategic military outpost designed to withstand nuclear or chemical attacks during potential conflicts in the Baltic Sea region. Visitors traverse the original corridors, which retain authentic period communication equipment, command consoles, and military maps. The site was classified as a top-secret military facility until the early 21st century, when it was declassified and opened to the public. Much of the original ventilation and electrical infrastructure remains intact, providing insight into mid-20th-century defensive engineering. Guided tours emphasize the operational history of the base and the conditions under which soldiers lived in isolation. The bunker is located near the Swina River delta, tucked away from the main tourist beaches.

Wear a light jacket as the temperature inside the tunnels remains consistently low regardless of the weather outside.
Plan to follow the guide closely, as the tour covers a specific route through narrow, winding corridors.
Wear comfortable, flat footwear with good grip, as some sections of the floor may be uneven or damp.
Do not attempt to explore the complex without a guide, as the tunnel network is extensive and strictly restricted.
Tours are mandatory and run at scheduled intervals; check for potential seasonal hour adjustments in winter months.
Do not touch the historical equipment or write on the bunker walls.
