The baths followed the "great Imperial baths" blueprint for Roman baths. They were more a leisure centre than just a series of baths. Besides being used for bathing, the complex also offered facilities for taking walks, reading/studying, exercise and body care. The main building stood in the centre with no connections to the surrounding walls, which housed the cisterns, two symmetrical libraries (south), two large "exedras" (east and west) and "tabernae" (shops) to the north. The surviving library measures 38 by 22 meters. Between the outer wall and the central complex were gardens ("xystus").
