The baths remained in use until the 4th century AD. The first room one encounters on entering, passing through a large rectangular hall that perhaps served as a changing room, is the frigidarium. In it are three baths, two small semicircular and one quadrangular. On the wall of the frigidarium is the fresco that gave the complex its name, with scenes of hunting in the amphitheatre. The figures of venatores (hunters) armed with spears and animals are flanked by their respective names. The walls of the quadrangular basin also preserve a beautiful fresco with a Nilotic scene, while one of the semicircular basins preserves large fragments of the mosaic decoration of the vault. The octagonal tepidarium hall has an almost entirely preserved domed roof.
