Athens

The cultural center of Greece, where Paul spoke to the Areopagus.

What the sources say, and how sure we are

The text says
Paul is distressed by the idols in Athens, debates in the marketplace, and speaks to the Areopagus, citing an altar to an unknown god and a Greek poet.Acts 17:16–34
Outside evidence
Ancient writers mention altars to unknown gods in Athens, and the line in Acts 17:28 matches a verse in the poet Aratus. The agora and the hill of the Areopagus can be visited.Acts 17:23; Acts 17:28; Aratus, Phaenomena 5
Debated
Scholars debate whether Paul spoke on the hill of the Areopagus or before the council that met there, and how much his speech was shaped by Luke.Acts 17:19
