The town of Nessebar is one of the oldest towns in Europe. It is the successor of the ancient Thracian settlement called Mesambria founded in the Second century AD. Its name means town of Melsa. Since 510 AD it was turned into Greek colony town by Dorian settlers. They called it Mesambria. There was a theatre and a temple of the Greek God Apollo in it. Brass and silver money were coined there, and in the third century AD - golden ones. It was occupied in 72 AD by a Roman garrison. It started to play important role again in III-IV century. In the year 812 Khan Krum conquered the town. In 864 Boris I yielded the possession of the town to Byzantine, but King Simeon captured it again. Since XI century the Slav name Messebar or Nessebar has been used together with the original name Mesambria. The churches in Nessebar are 41. Not all of them have preserved their full brilliance but even their present condition strongly impresses tourists. One of the oldest sights is the Basilica situated on the seashore, built probably at the beginning of 5 th century.
