The town is situated on a small plain in the main section of the Sredna Gora Mountains, 360 meters (1170 feet) above sea level. It is protected on every side by mountain slopes; it is wide open to the sun of Thrace from the south; the air is extremely clean due to the lack of industrial enterprises.
The first residents on the plain were the Thracian tribe of Bessi, and after them Macedonians, but Hisarya reached its zenith during the time of the Romans. They built a city with wide streets, beautiful courtyards, villas for the aristocracy, marble baths, a sewerage system, and an amphitheater; they circled it with a strong fortified wall, which is well-preserved even today. They called it Augusta, Sevastopolis, Dioclesianopol and made it the third-largest city in the province of Thrace after Philipopolis (Plovdiv) and Beroe (Stara Zagora). Between the 9th and 14th century it was within the territory of the Bulgarian state and called Toplitsa. When the Ottomans captured the city, it was completely destroyed. The Turks did not value it for its natural resourses until the 17th century, when they restored it and gave the city its present name - Hisar (tur. fortress).
All monuments of culture in Hissarya are exhibited in a beautiful and very convenient for the visitors park environment.
The Archaeological museum in Hissarya has at its disposal skilled guides who give a competent information to the studious tourists. Hissarya archaeological heritage is unique. There is no other place with so completely preserved monuments of culture from the Roman and Early Byzantine epoch with all their elements and multiformity.
