Mesembria

[5] These statements may, however, be reconciled by supposing that the Thracian town was originally colonized by Megarians, and afterwards received additional colonists from Byzantium and Chalcedon.

Mesembria was one of the cities, forming the Greek Pentapolis on the Euxine, the other four being Odessus, Tomi, Istriani and Apolloniatae.

Mesembria is rarely mentioned in history, but it continued to exist till a late period, being recorded by Pomponius Mela,[6] Pliny the Elder,[7] and Ptolemy,[2] and appearing in the Peutinger Table.

[8] The Dorian colonisation is dated to the beginning of the 6th century BCE, and evidence shows that it was an important trading centre from then on and a rival of Apollonia (Sozopol).

Her work led to the identification of five chronological periods of urbanization on the peninsula surrounding Nesebar through the end of the second millennium BCE, which included the Thracian protopolis, the Greek colony Mesambria, a Roman-ruled village to the Early Christian Era, the Medieval settlement and a Renaissance era town, known as Mesemvria or Nessebar.
