Antigonea , also transliterated as Antigonia and Antigoneia, was an ancient Greek city in Chaonia, Epirus, and the chief inland city of the ancient Chaonians. It was founded in the 3rd century BC by Pyrrhus of Epirus, who named it after one of his wives, Antigone, daughter of Berenice I and step-daughter of Ptolemy I of Egypt. In 198 BC the Romans defeated the Macedonian armies of Philip V. The inhabitants of Antigoneia had sided with the Macedonians and so when the Romans were victorious over the Macedonians in 167BC they decided to punish those who had fought against them. The Romans set fire to 70 towns in Epirus including Antigoneia and the town was not rebuilt. A newly discovered church, on the floor of which there is a mosaic of Saint Christopher and a Greek emblem, testifying to the city’s existence in the palaeo-Christian period, was the last building constructed in ancient Antigonea. It was destroyed during Slav assaults in the 6th century AD.
