The site features the remains of a city founded by Dorian Greeks in the 5th century BC on the northern shores of the Black Sea. It encompasses six component sites with urban remains and agricultural lands divided into several hundreds of chora, rectangular plots of equal size. The plots supported vineyards whose production was exported by the city which thrived until the 15th century. The site features several public building complexes and residential neighbourhoods, as well as early Christian monuments alongside remains from Stone and Bronze Age settlements; Roman and medieval tower fortifications and water supply systems; and exceptionally well-preserved examples of vineyard planting and dividing walls. In the 3rd century AD, the site was known as the most productive wine centre of the Black Sea and remained a hub of exchange between the Greek, Roman and Byzantine Empires and populations north of the Black Sea. It is an outstanding example of democratic land organization linked to an ancient polis, reflecting the city’s social organization.
