Mainz Underworlds

Up until now, only adepts knew about the subterranean passages and vaults in Mainz’s underworld. Who built them and why for that matter? And for what reason are there so many underground “water castles”?

Discover the Mainz underground and learn about the diverse history of the underworld: the “Mainzer Unterwelten e.V.” association offers regular tours with various focal points – submerge yourself and become an insider.
