Guided tour through the underground corridors of the citadel

The citadel’s casemates form one of the largest winter habitats for bats in Europe. They are therefore only accessible to visitors for three months a year. The vaulted corridors with their thick walls were built for defensive purposes.




During your visit to the casemates of the Bastion König, you will not only explore one of the oldest areas of the citadel, most of which has been preserved in its original state, but also a place of cinematic interest, including “Der Hexer” by Edgar Wallace filmed here in 1964.
