Corinth

Peter may have visited Corinth, and maybe there existed a party of "Cephas". First Corinthians suggests that perhaps Peter visited the city of Corinth, located in Greece, during their missions.

Dionysius, bishop of Corinth, in his Epistle to the Roman Church under Pope Soter (A.D. 165–174), declares that Peter and Paul founded the Church of Rome and the Church of Corinth, and they have lived in Corinth for some time, and finally in Italy where they found death:

You have thus by such an admonition bound together the planting of Peter and of Paul at Rome and Corinth. For both of them planted and likewise taught us in our Corinth. And they taught together in like manner in Italy, and suffered martyrdom at the same time.
