The site of Doliche is located close to the modern city Gaziantep in South-Eastern Turkey. 

The city center is located on Keber Tepe, a flat hill on the outskirts of the modern village of Dülük. On the outskirts of the village there is also a quarry, the remains of a Roman water conduit and an extensive necropolis. On the nearby Dülük Baba Tepesi, a hill of 1204 m height, the remains of the main sanctuary of the roman city is located, the Sanctuary of Iuppiter Dolichenus. The temple goes back to an Iron Age dated open-air sanctuary for a weathergod. The pottery also attests an intensive use of the Dülük Baba Tepesi during the Hellenistic period. After the destruction of the Roman temple for Iuppiter Dolichenus, a monastery was build on the hilltop. This monastery can be identified as the Monastery of Mar Salomon. It was in use at least until the early 12th century CE. The excavations on the Dülük Baba Tepesi ended in 2015.

The excavations on the Keber Tepe started in 2015 and could expose a huge bath-complex, the archive of the city, a monumental temple of the roman period, and an early-christian basilica. Already in the 90s a big Mithraeum was discovered on the Keber Tepe.
