Philippi was first named by Philip II in 356 BC when he seized the city to control nearby gold mines that would fund his Macedonian empire and his son Alexander's conquests. Then it was a Roman colony (42 BC, after the Battle of Philippi where Octavian defeated Brutus and Cassius - the last significant resistance to one-man rule in Rome). Then it was the city where Paul was arrested and beaten. Then it was a Byzantine Christian center producing wine continuously until the 12th century. Every era of Western civilization is physically layered in this site - Greek military, Roman imperial, early Christian, Byzantine. The forum you're standing in was simultaneously a Macedonian agora, a Roman colonia forum, and eventually a space hemmed in by early Christian basilicas. UNESCO called it "a smaller reflection of Rome" which is exactly what the Romans intended. Enter the main archaeological zone from the site ticket office on the national road. The Roman forum (agora) is immediately visible from the entrance. Walk the full forum perimeter. In one circuit you'll pass: Greek architectural remnants, Roman civic inscriptions in Latin, an early Christian basilica apse, and Byzantine-period modifications. Count the different architectural styles in the stones around the same space.
🔄 BACKUP: The site is open and walkable even when the ticket office is staffed minimally. The information panels at the forum entrance give a complete chronological overview.
