In Świnoujście - on the island of Wolin - there is a military facility whose secret has been closely guarded for years. It is a network of underground corridors connecting several large shelters, hidden under coastal dunes. Due to the specifics of the object, the tour lasts about two hours and it takes place only with a guide. Depending on the season, the Underground City is open at certain times (the exact distribution of entries is on the attractions page). In the case of organized groups, it is possible to book and set an individual date for the visit.
