When they had passed through Amphipolis and Apollonia... Acts 17:1
City: Both cities were on the Egnatian Way, a major route running east-west across present-day
northern Greece. Each was about a day's journey from the next (30 miles). The road is still visible
today at several locations in Philippi and Apollonia. (NIV Study Bible:1678)
Summary: Paul and Silas passed through each of these cities on their way from Philippi to Thessalonica.
