An excerpt from the article 11 facts about Pamukkale

Sick people who came in large numbers to Hierapolis for treatment did not always return home. Some did not recover and their bodies were buried in the local cemetery. The dead were buried in three places: north, south, and east of the city, a short distance from St. Paul’s martyrium.
