In the 4th century A.D., Poimenios, the Roman governor of nearby Corycus, (modern Kızkalesi) commissioned a bath and baptism complex in Porto Calamie.

The source of the bath water was an underground stream from the sinkhole Cennet, which is in the Taurus Mountains, 1.1 kilometres (0.68 mi) northwest of Porto Calamie.

[1] An inscription at the entrance of the bath reads: Dear Visitor, if you wonder who has discovered the origin of this miraculous water, know that he is Poimenios, the friend of the emperors and the honest administrator of the holy islands.The emperors mentioned were probably Arcadius (378-408) and Honorius (384-423).

The mosaic depicts three Graces, Aglaea, Euphrosyne and Thalia, and a couple of partridges and doves.
