The history of the town is mainly connected with the Roman Empire. When the Roman first arrive they find a small Thracian settlement but its thermal springs make it a favourite residence of the emperors. Hissarya is established as an administrative centre in III AD and a fortress wall is erected all around the town and it was called Auguste.
It has been the residence of Maximian, Galerius, Licinius and Diocletian. Diocletian renovated the fortress and gave it his name – Diocletianopolis. The town was really flourishing and today it is one of the finest examples of Roman settlements on the Balkan Peninsula.
