Narlıkuyu is a town in Silifke ilçe (district) of Mersin Province. Narlıkuyu is 20 kilometres (12 mi) from Silifke and 65 kilometres (40 mi) from Mersin. It is situated in a small Mediterranean bay which is fed by freshwater. The museum is actually a closed area of mosaic and it is situated just at the back of the restaurants at .
During the Roman Empire, Narlıkuyu was called Porto Calamie. In the 4th century A.D., Poimenios, the Roman governor of nearby Corycus, 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. The bath survives and, in 1976, a 65.28 m2 (702.7 sq ft) building was constructed to house the bath. The building is now under the supervision of the Ministry of Culture as a free-of-charge museum.
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.— unknown, 
The bath floor is a mosaic. The mosaic depicts three Graces, Aglaea, Euphrosyne and Thalia, and a couple of partridges and doves. The local name of the mosaic is Üç Güzeller (English: Three beauties) The mosaic refers to the mythological story of the baptism of Aphrodite.
