HISARYA

The town of Hissarya is located in the central part of Bulgaria, under the southern slopes of Sredna Gora, at 346 m above sea level. It is 44 km north of the regional town of Plovdiv and 24 km south of the town of Karlovo. The relief is formed by the smooth transition from the slopes of Sredna Gora to the Upper Thracian lowland.
Hissarya is distinguished by 22 mineral springs with different physico-chemical characteristics and temperature and with proven healing properties - 16 natural and 6 deeply drilled. All waters are clear, colorless, thermal and with pleasant drinking and taste qualities. In terms of chemical properties, they are sodium sulphate-hydrocarbonate, with a high alkaline reaction and low hardness. The content of hydrocarbons and sodium is predominant. They contain minerals from 170 to 275 mg / l and fall into the category of low-mineralized waters (less than 2 g / l).
Hisarya (called Diocletianopolis, Vetus Augusta Aria, Termeitisina, Toplica) has a rich thousand-year history. The favorable climate and mineral waters have attracted people to these places since ancient times. There was a prehistoric settlement here before V-IV millennium BC. The later Thracian settlement around the mineral springs was part of the Odrysian kingdom. Healing and religious sanctuaries (nymphs) were built around the mineral springs. The great Thracian cult facilities near Starosel date from this period.
