In the Kommandantenhaus on the Petersberg, an exhibition that thrives on interaction awaits you. Embark on a journey of discovery through the entire historical development of the Petersberg. Here, for example, the monastic period, the history of the fortress and the life of the soldiers, right up to the use of the citadel in the GDR, are discussed. Through multimedia, interactive offerings, such as video installations, sounds, infographics, or models, you can experience the moving history of the Petersberg and the fortress first-hand. An exciting challenge with tricky questions provides additional fun.
