The port that was founded by Thassians in the late 7th century BC was a natural bay on the west coasts of the Panagia peninsula, which has nowadays disappeared under the embankments.
The port kept the communication to the entire Greek world of Aegean and Asia Minor alive, and not only goods but also spiritual messages about religions of the Greek world and the East reached the city, whereby the highlight was in 49/50 AD the arrival of Apostle Paul, who brought the message of the new religion in Europe.
