Mersin

About Mersin

Mersin stretches along the eastern Mediterranean coast of Turkey at the foot of the Taurus Mountains, encompassing a modern port city, ancient Cilician ruins, sea fortresses, sweeping beaches and highland plateaus. The city itself is Turkey's busiest container port and a lively commercial center, with a long seafront promenade, a vibrant food scene and easy access to some of Anatolia's most remarkable historical sites. Kızkalesi — the offshore island castle in a turquoise bay — is the province's most photographed landmark. Inland, the Cennet ve Cehennem sinkholes, the temple city of Uzuncaburç, the rock reliefs at Adamkayalar and the spectacular Alahan Monastery cling to the limestone ridges of the Taurus. Tarsus, birthplace of St Paul and once a great Hellenistic and Roman metropolis, lies just 27 km east. The coastal strip produces citrus, bananas and strawberries, and the local table is famous for its seafood, hummus and Tarsus kebabs. The province offers something for every traveler: budget backpackers find cheap guesthouses near Kızkalesi beach, history enthusiasts could spend a week among Roman and Byzantine sites, and sun seekers spread out along beaches from Erdemli to Aydıncık.

Best places to visit in Mersin

The 22 destinations our editors recommend — from iconic landmarks to under-the-radar finds.

Kızkalesi (Maiden's Castle)

A Byzantine fortress built on a small islet just off the Kızkalesi coastline, connected historically to a matching mainland fortress (Korykos) that still stands on shore. The castle was refortified by the Armenian Kingdom of Cilicia and later by Crusader and Ottoman forces, and its walls and towers remain largely intact despite standing in open water for centuries. Boats run out from the beach in front of the modern town, so the visit combines a short crossing with a walk around the ramparts.

Uzuncaburç (Ancient Olba / Diocaesarea)

The mountain ruins of Olba, later renamed Diocaesarea, an inland sanctuary city built around a Hellenistic temple to Zeus Olbios and expanded by Rome into a full city with a colonnaded street, a monumental gate, a theatre, and a nymphaeum. Its columns still stand in rows along the former main street, giving a clearer sense of the ancient street plan than most ruins in the region. The setting is a working village, with the ruins scattered among houses and fields rather than fenced off as a single park.

Cennet ve Cehennem (Heaven and Hell Sinkholes)

Two large limestone sinkholes a short walk apart: Cennet (Heaven), a deep chasm you descend by a long stepped path to a Byzantine chapel and a cave mouth at the bottom, and Cehennem (Hell), a sheer-sided pit you view only from a railed rim above. Local tradition ties the sinkholes to the myth of Typhon being cast into the underworld, and the chapel at the bottom of Cennet marks the site as a place of pilgrimage in Byzantine times. The descent into Cennet is the main physical activity here, not a passive viewpoint stop.

Tarsus — Roman Gate, St Paul's Well & Waterfall

Three separate points within old Tarsus tied to its Roman and biblical past: the Roman Gate (traditionally called Cleopatra's Gate) marking a historic entrance to the city, St Paul's Well in the old bazaar district associated with the apostle's traditional birthplace, and the Tarsus waterfall on the edge of town. Tarsus was a major Roman provincial capital, and the gate and surrounding old quarter reflect that layered history alongside the city's later Ottoman-era market streets. The three sights sit close enough together to combine into a single walking stop in the old town.

Alahan Monastery

A fifth-century Byzantine monastic complex perched on a ledge in the Taurus Mountains above the Göksu valley, built in two main clusters of churches, a baptistery, and monastic quarters connected by a colonnaded walkway. Its carved lintels and column capitals, some depicting animals and biblical scenes, are unusually well preserved for a mountain site of this age. The remote setting above the gorge is as much a reason to visit as the carvings themselves.

Adamkayalar Rock Reliefs

A set of Roman-era rock-cut reliefs carved into a cliff face in a valley inland from Kızkalesi, depicting local notables, warriors, and family groups in Roman dress, thought to have marked tombs of the regional elite. The reliefs are strung along a stretch of cliff reached on foot down a rough valley trail rather than displayed at a formal site. Their isolated, unrestored setting is part of what makes them different from the more visited ruins along the coast.
