"Diocletianopolis" – the Ancient Roman Town in Hisarya, Bulgaria (PHOTOS)

Diocletianopolis is a beautiful and magnificent ancient Roman town in the region of Thrace, nowadays Hisarya, in Bulgaria. The architecture and fortifying system of the Roman town are among the most original and well preserved in Europe.

Fortress walls around the city were built at the beginning of the 4th century and had a total length of around 2,300 meters, a thickness up to 4 meters and a height of 12.5 meters. They have enclosed an area of 20,000m2.


Archaeology shows that the site was inhabited from 6,000 years BC and later a Thracian settlement was developed there. In the 1st century AD, Thrace was conquered by the Romans and that is how the settlement became a Roman city. It was first called Augusta.

After the fall of the Roman Empire, at the end of 6th to the beginning of the 7th century, it was destroyed during invasions of Slavs and Pannonian Avars. Today most of the city lies buried under a green park where you can take a walk and enjoy the nature.

The city has hot mineral springs, which were used for treatment. The Thermae are still fed by hot springs and have swimming pools. You can pay for a ticket and walk inside to see closer the rooms where people used to take a hot mineral bath and talk to each other. Pretty near, you can pour mineral water, which is recommended for drinking as it has healing powers. Turning right, you will see an ancient Amphitheatre, and while walking outside of the gates, you will probably hear music from a concert, which is held in the outside Amphitheatre, that is working and gathering people from all over the world.

The main gate is called the “Camels”. From there was the road to the main administrative center of the province - Thrace - Philippopolis.

The archaeological excavations have brought evidence about the locating of five cemeteries. Close to the town is situated the Roman tomb, that is preserved in original and it is open for visitors. It has a long corridor with a mosaic floor.
