The South Bath was built in the 2nd century AD. The associated aqueduct probably already existed there. Today there are only inconspicuous remains of walls left.
The Therme reflects the construction, conversion and completion work of various phases from the 2nd century AD to the 5th century AD.
The walls were decorated with marble slabs, statues and mosaics of deities of Greek mythology such as Athena, Aphrodite, Nemesis and Aklepios. In the tepidarium was placed a group of statues of the three Graces, Euphrosyne (the "Merry"), Thalia (the "Flowering") and Aglaia (the "Radiant"). These statues are now in the Archaeological Museum in Antalya.
The excavations at the South Spa, one of the two largest baths in the city, were carried out between 1978 and 1985.
