Outside the city is a graveyard which one can visit even today. This graveyard was flanked on one side by the north road going towards Tripolis-Sardes and on the other by the south road which followed the direction of Laodicea- Colossai graveyards along roads were traditional under Romans.
To the east of the city of the slope is another graveyard. These graveyards contained tombs of travertine. The marble which was either of local origin or transported from the surrounding region was used only in the fabrication of sarcophagi of which we have here a good many specimens. The region to the north east and in the confines of the city must have been the first burial ground. The limits of the region reserved to the death in the confines of the city in 1st century is comprised later within the city itself.
The funerary monument dating from the times of Julius Claudius dedicated to an important person remained intact because of the respect due to him. This monumental tomb which is in the necropolis of Hierapolis resembling a sanctuary is a typical example of an edicule. Some had columns in line on an elevated footing on which rested the sarcophagus like at Mylasa, Iasos and Termessos. The few vestiges remain. The inside of the tomb which looked like the interior of Heroon consisted of a rectangular chamber surrounded on four sides by seats in rows of seats in the shape of a triclinius.
The entry into the tombs section is through a vestibule linked with a decorated structure with engravings. The door has a panel f'ixed with hinges. The family tombs are in general surrounded by a small garden while other tombs have been added at a later date. To the east of the region with the hellenistic city stretching dating from the times of Domitianus is a poormen's graveyard. Tumuli like those in Anatolia and Thrace can be found in Hierapolis.
These had been made heaping up earth on a rectangular vaulted chamber. Inside the chamber are three funeral couches. A dramos provides entry to the chamber . The type of tomb with edicule and fronton date rather from Ist century .In IInd and IIIrd centuries the footings on which rested the sarcophagi were made more conspicuous with a view to transforming the dead into heroes. The sarcophagus was for the one contained in it.
The representations painted on walls surrounding Hierapolis from the three sides form the greatest part of the inscriptions of the city . Sometimes one encounters them on the constructions themselves. Nearly all the inscriptions speak of the control of the justice. In the epitaphs the biography of the deceased has been given no large room in comparison with those of other sites.
The names and the relationship of the buried are clearly inscribed, while poetical expressions are very rare. Some among them mentions also the profession of the buried. In the northern necropolis are sarcophagi bearing epitaphs of round tumuli, and quadrangular tombs of stone resembling houses. The number of tombs is above one thousand. Tombs dating from hellenistic and roman periods were sacked.
