A Roman colony in Macedonia and the first European city where Paul preached.

What the sources say, and how sure we are
- The text says
After the vision at Troas, Paul comes to Philippi, meets Lydia by the river, and is imprisoned and freed. The church there later supports him and receives a letter from him.Acts 16:9–40; Phil 1:3–5; Phil 4:15–18
- Outside evidence
Philippi lay on the Via Egnatia and became a Roman colony after Octavian and Antony defeated Brutus and Cassius there in 42 BC, as Acts 16:12 implies. Excavations uncovered the forum and other buildings.Via Egnatia; Acts 16:12
- Debated
A site shown as Paul’s prison in Philippi is a Roman structure of uncertain use. The identification with the prison in Acts is traditional and unconfirmed.Acts 16:23–24
