What is the importance of Philippi being situated on the Egnatian Way?

Philippi was an important city in eastern Macedon which flourished in the Hellenistic, Roman, and Byzantine Periods. Situated between the Strymon and Nestos rivers, the city was valued in antiquity for its nearby gold mines. Site of the famous Battle of Philippi at the end of the Roman Republic, the city prospered in the Roman imperial era and, after a visit from St. Paul, became an important centre of early Christianity. Philippi continued to flourish as a major Byzantine city. Today the archaeological site has substantial remains including a theatre and four basilicas.
