The baths were constructed during the time of Emperor Caracalla in honor of the god of medicine, Asklepios. The unusually large complex has three main divisions: a frigidarium (cold room), a caldarium (hot room), and a tepidarium (tepid room). The frigidarium had a pool and changing rooms, the caldarium contained a washing area and a sudatorium (sweating area), and the tepidarium was used primarily as a room for relaxing. There are also courtyards, hearths, service areas, and storage in the complex, and a renewal in funding for excavations and restoration projects will be revealing more and more.
