Massive structures discovered under 3,000-year-old garrison

Massive structures under the Zerzevan Castle, a 3,000-year-old Roman garrison in the southeastern province of Diyarbakır, have come to light during the ongoing excavation works at the site.

Excavation works that started in 2014 at the castle have brought to light numerous artifacts.

Under the site, residential areas, water cisterns, a church, a shelter, and Mithras Temple have been recently discovered.

The temple is of particular importance as it is the first temple of its kind discovered at the eastern border of the Roman Empire.

"Through the excavations, we will be able to find answers to some of the mysteries of underground structures," stated Aytaç Coşkun, the head of the excavation team.
