A complex of wartime fortifications ordered by Hitler and built in 1934-38. Bunkers with reinforced steel walls are interconnected by underground corridors.

The fortifications were awarded in 2005 with the prestigious certificate of the Polish Tourism Organization, as a tourism product named “Świnoujście – a fortress on islands”.

Hitler’s headquarters at Gierłoż, known as Wolf’s Lair, is one of the most sinister places in the region, but it attracts many tourists because of its recent historical associations.
