Visit April 2017

Mainz has a rich roman history as military fortress.

Some sites are still visible such as the theatre (not very well maintained alas) and the excellent maintained, not so long ago discovered, Isis temple, an undergroundsmall museum in a shopping mall with the applicable name Romer Passage.
