Heraclea Lyncestis, also spelled Herakleia Lynkestis (Ancient Greek: Ἡράκλεια Λυγκηστίς; Latin: Heraclea Lyncestis; Macedonian: Хераклеја Линкестис), was an ancient Greek city in Macedon, ruled later by the Romans. Its ruins are situated 2 km (1.2 mi) south of the present-day town of Bitola, North Macedonia. In the early Christian period, Heraclea was an important Episcopal seat and a waypoint on the Via Egnatia that once linked Byzantium with Rome through the Adriatic seaport Dyrrachium. Some of its bishops are mentioned in synods in Serdica and other nearby towns. The city was gradually abandoned in the 6th century AD following an earthquake and Slavic invasions.
It was founded by Philip II of Macedon in the middle of the 4th century BC. The city was named in honor of the mythological hero Heracles. The name Lynkestis originates from the name of the ancient kingdom, conquered by Philip, where the city was built.
