Podziemne Miasto Osówka

The Underground City of Osowka is a mysterious complex of World War II-era underground corridors and halls, part of the 'Riese' project.

It's a place full of historical riddles - it's still unclear whether it was meant to be Hitler's quarters or a weapons factory. Visitors can choose between the historical route and the extreme route, where a torchlight crossing of flooded corridors awaits.

The temperature inside is around 8°C, so warm clothing and waterproof boots are a must. For history buffs and adventurers, Osowka offers an unforgettable experience in a mysterious underground world.
