The family tombs appear to have been damaged during construction work in the 1950s and 1960s.
Yulian Meshekov, leader of the archaeological excavations, said that the tombs were cut practically at foundation level, with little of their higher reaches preserved, probably as a result of the construction work in those past decades.
The tombs are believed to date from the early Christian period, between the fourth and sixth centuries, when it was not customary to leave burial gifts. There were no remains in them, which means that over the centuries, they had been subject to vandalism.
