Named after the god Apollo, Apollonia was founded by the Greeks in 588 BC and blossomed into an important city-state. The city fared even better under the Romans, and was famous for its school of philosophy, which educated the future Emperor Augustus. A series of disasters forced the population to abandon the city. Today, visitors are free to roam the ruins, including a small theatre and the pillars on the restored facade of the 2nd century administrative centre. For a more detailed look, the 14th-century monastery of St. Mary displays over 688 important artefacts, including pottery, coins and statues.
