A military base in Roman times, the site has been undergoing archaeological excavation since 2014, and in 2017 a 4th-century temple to Mithras was discovered. The site contains the remains of 200m-long walls up to 15m high and a 21m watch tower, with a number of buildings to cater for some 1,000 occupants. Jewellery found here shows that there were resident families. An underground church and shelter for up to 400 people, with Aramaic inscriptions, have been excavated together with a series of subterranean passages.
