Sozopol ( , ) is an ancient seaside town located 35 km south of Burgas on the southern Bulgarian Black Sea Coast. Today it is one of the major seaside resorts in the country, known for the Apollonia art and film festival (which takes place in early September) that is named after one of the town's ancient names. The busiest times of the year are the summer months, ranging from May to September as tourists from around the world come to enjoy the weather, sandy beaches, history and culture, fusion cuisine (Balkan and Mediterranean), and atmosphere of the colourful resort. Part of Burgas Province and administrative centre of the homonymous Sozopol Municipality, as of December 2009, the town has a population of 5,410 inhabitants. Name The original name of the city is attested as Antheia (Ἄνθεια in Greek) but was soon renamed to Apollonia (Ἀπολλωνία). At various times, Apollonia was known as Apollonia Pontica (Ἀπολλωνία ἡ Ποντική, that is, "Apollonia on the Black Sea", the ancient Pontus Euxinus) and Apollonia Magna ("Great Apollonia"). By the first century AD, the name Sozopolis (Σωζόπολις) began to appear in written records. During the Ottoman rule the town was known as Sizebolu, Sizeboli or Sizebolou. History Sozopol is one of the oldest towns on Bulgarian Thrace's Black Sea coast. The first settlement on the site dates back to the Bronze Age. Undersea explorations in the region of the port reveal relics of dwellings, ceramic pottery, stone and bone tools from that era. Many anchors from the second and first millennium BC have been discovered in the town's bay, a proof of active shipping since ancient times. The town was founded in the 7th century BC by Greek colonists from Miletus as Antheia (). The town established itself as a trade and naval centre in the following centuries and became one of the largest and richest Greek colonies in the Black Sea region. Its trade influence in the Thracian territories was based on a treaty dating from the fifth century BC with the Odrysian kingdom, the most powerful Thracian state. Apollonia became a legendary trading rival of another Greek colony, Mesembria, today's Nessebar. The name was changed to Apollonia, on account of a temple dedicated to Apollo in the town. There were two temples of Apollo Iatros (), meaning healer in Greek. One from the Late Archaic Greece and the other from the Early Classical
