The amenities at the Baths of Caracalla were impressive. The main attractions were three bathing chambers: the frigidarium (cold pool), the tepidarium (moderate temperature pool) and the caldarium (hot pool). There was also a roofless, Olympic-size swimming pool. The complex had two libraries; one for Greek and another for Latin. Also available were two exercise gyms plus steam baths, saunas, sports courts, massage rooms, entertainment areas, retailers and restaurants. In the center was a great hall with a vaulted ceiling. No expense was spared with decorations. Most of the rooms were beautifully appointed with marble, sculptures, mosaics, frescos and columns. The outside gardens and walking paths were equally attractive.
