The archaeological site: Founded at the end of the Bronze Age by a Thracian tribe, Nessebar is one of the oldest towns on the western Black Sea Coast. Its name, which was originally Mesambria, originates from the Thracian words “Melsas”, the name of the legendary founder of the settlement and “bria”- the Thracian word for town. It is situated on a small peninsula (about 0.5 sq. km) that was connected to the mainland by a narrow isthmus. According to ancient sources, Nessebar had two harbors – one on its north and another to its south. Mesambria’s first Greek colonizers were of Dorian origin who settled there at the end of the 6th century BCE. The town grew quickly and became one of the most powerful Greek colonies along the western Black Sea Coast. It had several temples, a gymnasium, a theatre, massive administrative buildings and corresponding infrastructure. Mesambria was also gradually surrounded by massive fortification walls. It reached the peak of its prosperity in the 3rd – 2nd centuries BCE, at which point it even minted its own gold coins. Commercial links connected it to towns from the Black Sea, Aegean, and Mediterranean coasts. Numerous imported precious artifacts now displayed in the Archaeological Museum of Nessebar provide material expression of the site’s rich economic, cultural, and spiritual life in this period.
In 72 BCE, the town was conquered by Roman armies without resistance. After a temporary occupation in the beginning of the 1st century CE, it was included permanently within the limits of the Roman Empire. After the capital was moved to Constantinople in 324 CE and Christianity was accepted as the official religion of the Empire in 313 CE, favorable conditions arose for the renaissance of the town. New Christian basilicas, fortification walls, and water supply lines were built in the following centuries.
The city was besieged and taken for the first time by the Bulgarians in 812 CE. It was in a border region between the Byzantine Empire and the Bulgarian Kingdom and periodically changed hands between the two powers. During the 12th and 13th centuries, active trade links were developed between Nessebar and some Mediterranean and Adriatic towns, such as Constantinople, Venice, Genoa, Pisa, Ancona, and Dubrovnik, as well as with the kingdoms north of the Danube region. During almost its entire Christian history, Nessebar was the seat of a bishop. Many churches and monasteries were built in the city and its surroundings reflecting its prosperity and richness.
Project description: The main scientific and research questions are:
1) What is the evolution of the landscape of the Nessebar peninsula;
2) What part of the ancient town was destroyed by abrasive processes;
3) What are the preserved archaeological structures underwater and what is their age;
4) Where were the harbors of the town;
5) What is the state of the structures underwater and what are the possibilities for their exhibition and socialization in order to turn them into a destination for cultural tourism, etc.
Project History: In 2017, after a gap of 33 years, the Centre for Underwater Archaeology resumed regular archaeological research in Nessebar with the support of the Ministry of Culture and the Balkan Heritage Foundation.
Results: The new archaeological surveys and excavations revealed new parts of the fortification system – massive block walls probably from Hellenistic period and stone and mortar and opus mixtum walls from the Byzantine period. A newly discovered massive stone jetty is the first structure associated with the ancient harbors of the town found so far.
