The structure is part of the two rooms juxtaposed to the thermal bath complex and built to allow access to the baths from outside, directly from the porticoed courtyard.
The small apsidal hall is equipped with three openings: the first entry from the porticoed courtyard, the second to access the large latrine, and the third leads to a small antechamber to enter the baths.
A finely decorated public place, featuring a mosaic floor with sophisticated geometric designs, characterised by the presence of an apse in the north wall.
During archaeological excavations, small fragments of a white marble statuette of a Venus Anadyomene were found in this room, hence its name.
