Amphipolis

Amphipolis (meaning city on both sides) was a major Macedonian city situated on a peninsula almost entirely surrounded by the Strymon River, approximately thirty-three miles southwest of Philippi. Founded as an Athenian colony in 437 BC, it became the capital of the first district of Macedonia under Roman administration. Paul and Silas passed through Amphipolis on their journey from Philippi to Thessalonica during the second missionary journey (Acts 17:1), apparently without stopping to establish a congregation — suggesting there was no synagogue there to serve as the customary starting point for Paul's ministry.
