The Thermes, or baths were a complex built on the east side of the athletic complex where the gymnasium and palestra (wrestling school) were, during the latter part of the second century AD, and have been very well preseved. Their walls were decorated with marble and the floors were covered with mosaics. A small vaulted room, the laconicum or sudatorium (a type of sauna) was turned into a baptistry in the late fifth century AD, around which a three aisled Christian basilica was built, and in the seventh century one of the north western bath chambers was turned into a tomb.
