The fort bath lay to the east of the fort, 50m away from the "porta praetoria", between the harbour and the fort walls.
The building complex consisted of several rooms that were laid out
in a row. The bath was
44.5m long and up to 19.45m wide, and made of gneiss. Several
praefurniums heated the large
rooms. After a cold bath (room
A), the bather moved through room B into the lukewarm bath C.
There was a decorated water basin of stone here. The largest room
D, the hot bath, had
two semi-circle niches. In these apses there were probably basins.
This room was decorated with colourful murals, geometric and floral
patterns decorated the walls. Shards of window glass were also
found: the southern windows provided additional warmth.
Many of the hypocaust tiles are stamped with the name of the "legio XXII Primigenia pia fidelis" which was stationed in Mainz and manufactured tiles in Frankfurt-Nied, among other locations. Parts of the pavement was made of waterproof concrete. It is likely that there were two cold-water basins in the northeast of the building. Sewage flowed from here through a canal to the Main.
Built c. 110 AD, shortly after the fort's construction
Current State: In 1968 the fort bath was moved to Nilkheimer Park.
