Ancient Messembria, is picturesquely located on a peninsula in the Black Sea. It was surrounded both of sea and land by thick stone-walls. Merchants from all over the Mediterranean area gathered here to take part in the festivals held in the local theatre and the temple of Apollo. Once an independent state, the town minted its own coins as early as the 5th c. BC. Legends say once there were 41 churches. Some of them have survived . The town is included in UNESCO’s World Cultural and Natural Heritage Program.
