Crypt – Sanctuary of the Flags (Fahnenheiligtum)

Underneath the parish church one can still find remains of the principia (the Roman headquarter building) with the Sanctuary of the Flags. According to the imperial cult a life size bronze statue of the current emperor was worshipped. The swearing-in ceremony of the soldiers was also held here. The massive stone base of the statue which is still located at its original place (in situ) can be regarded as unique. The room, where the military insignia and standards of the troop were kept, largely represents the state of the third century to this day.
