“By the Mediterranean shore, the cross and the moon goddess stand together;
the Göksu River sings a thousand-year story of Rome and saints.”City Introduction：
Silifke is located in southern Türkiye’s Mersin Province, a small city where ancient Roman heritage meets natural beauty. It lies between the clear waters of the Göksu River and the Mediterranean Sea.
Its history dates back to the 3rd century BCE. Originally known as Seleucia ad Calycadnum, it was an important port of the Seleucid Empire. Later, it became a crossroads of Roman, Byzantine, and Arab cultures, and during the Byzantine era it developed into an important Christian center.
Silifke is home to ancient bridges, fortresses, churches, and temple ruins, alongside blue coves, underground lakes, and limestone caves — truly a place where history and sea breeze coexist.
Top Attractions：
Silifke Castle
Built originally by the Byzantines and later expanded by the Crusaders and Ottomans, the castle stands on a hill overlooking the entire city and the Göksu River. Constructed from local white stone, it is the best viewpoint for sunset and panoramic scenery.
Inside, visitors can still see cisterns, underground chambers, and watchtowers. Legend says that during the Byzantine period, a sacred “Book of the Apostle,” said to have been gifted by Saint Peter to a local bishop, was hidden in a secret chamber beneath the castle.
Göksu River & Roman Bridge
The Göksu River flows through the city with striking clarity. The Roman bridge spanning the river has stood for nearly two thousand years and remains one of Silifke’s most recognizable landmarks.
It is said that Saint Paul stopped here during his missionary journeys, preaching for three days near the bridge and converting many residents to Christianity.
Temple of Apollo at Uzuncaburç
About 30 kilometers north of Silifke lies Uzuncaburç, the center of ancient Olba. The Temple of Apollo here is remarkably well preserved, with imposing columns that have earned it the nickname “the Parthenon of the Mediterranean.”
The site also includes a theater, triumphal arch, and agora. Nearby hills are believed to have been a cult site for the moon goddess Hecate. On full-moon nights, visitors still come to photograph the ruins beneath the moonlight.
Cennet ve Cehennem
(“Heaven and Hell” Sinkholes)
These dramatic limestone sinkholes west of Silifke were formed by massive underground collapses.
Cennet (Heaven) contains a small underground chapel and impressive stalactite formations.
Cehennem (Hell) is a deep, inaccessible chasm that, in Greek mythology, was believed to be an entrance to the underworld.
Legend says that Heracles battled the three-headed dog Cerberus here.
Nearby, Astım Cave (“Asthma Cave”) is known for its humid air, traditionally believed to help relieve respiratory conditions.
