City of Seleukeia was founded by Seleucus I Nicator in 3rd century B.C. in the west side of the Göksu River where today’s Silifke is located. Temple in the center of Silifke from Seleucia was built in 2nd century A.D. One column of the structure in Cointhian order still stands.
There was a Roman bridgebuild in the 1st century instead of the modern bridge over Göksu River passing through the middle of Silifke. Emperor Frederick Barbarossa was drowned in this river in 1290 A.D. during the third crusade.
Meryemlik which is a holy place of Christianity is located on Taşucu Highway, a few km south of Silifke. St. Thecla, student of St. Paul, hid in an underground cave which was converted into a church and became a sacred place because of the pagan pressures. It was used as a secret worshiped place until the release of Christianity in 4th century A.D. It was also an important visit center from the early years of the middle Ages. Church of St. Thecla, cisterns, sacred path and tomb ruins can be seen as well as this cave which was converted into an underground church in 4th century A.D.
