Which pagan cities did Paul take the Gospel to?

Paul took the Gospel to pagan cities including Antioch in Galatia, Derbe, Lystra, Ephesus, Philippi, Thessalonica, Berea, Athens, and Corinth. These were abject pagan idolaters who knew nothing of the God of creation. He preached Christ crucified among them, and many turned from their idols and believed.

Les explains that Paul faced insurmountable odds entering strange territory of pagan Gentiles who knew nothing of the God of the Bible or the little Jewish communities in those cities. The Jews never evangelized or took their knowledge to pagan Gentiles. Paul came into cities such as Antioch in Galatia, Derbe, Lystra, Ephesus, Philippi, Thessalonica, Berea, Athens, and Corinth—all abject pagan idolaters, morally corrupt, who knew nothing of the God of creation. Yet Paul preached Christ crucified, and those people turned from idols and became believers, staunch enough to be martyred by the hundreds. Les notes it was the power of God when the Gospel was preached.

What kind of cities did Paul visit on his missionary journeys?
