Overview

Hisarya (Хисаря, pronounced hi-SAH-ryah) is a health resort in Central Bulgaria, famous for its hot mineral springs and the Roman ruins in its heart. It's one of the oldest and largest balneotherapy resorts in Bulgaria, and probably the most famous one; it produces one of the most well-known brands of bottled mineral water in the country, dating back to the Communist era (1958). It's a small town (population of 6.5 thousand) nested in a mountain valley in the Sredna Gora range, east of the capital Sofia, north of Plovdiv and south-west of Karlovo.

Understand

There are 22 mineral water springs in Hisarya - 16 natural and 6 artificial (boreholes), with temperatures ranging . Their waters are alkaline, with low mineralisation (170-275 mg/l). The water of the Momina Banya spring contains low amounts of the radioactive gas radon (Rn, element 86) - 165 Eman/l, or 16,500 picocuries/l.

Name The name of the town originates from the Roman ruins: "hisar" is the Turkish word for "fortress" (a borrowing from Arabic), but with a Bulgarian definitive suffix (-ya) - "the Hisar". Confusingly, the use of the suffix is inconsistent - it's sometimes dropped even on road signs and in official documents (Хисар). The name is sometimes also spelled with a double S to make the correct pronunciation more clear - Hissarya, Hissar.

History The hot springs have attracted people there since prehistoric ages. Archaeologists have found remnants from a settlement dating back to the Late Neolithic Age (5th millennium BCE). In later times, the Thracians settled the area, which was conquered by the Roman Empire in the first century CE. The settlement grew into a city, which was destroyed by the Goths in the 3rd century, then rebuilt and fortified with thick walls in the 4th century. The exact name of the town hasn't been positively identified (e.g. by finding an inscription), but possible names mentioned in ancient sources include Augustae, Sevastopolis, and Diocletianopolis ("City of Diocletian", after the Roman emperor of that name), with indirect evidence suggesting the last option as the most probable. After the Empire split, the town remained a part of the Byzantine Empire until it was conquered by the First Bulgarian Empire in the 8th century. The fortress was likely destroyed during the Ottoman conquest of the Balkans in the 14th century.

Settlements in the area start appearing again in historical record in the 17th century. While in Hissarya the population was mainly Turkish, in the nearby villages Verigovo and Momina Banya (now quarters of the town) there lived enthusiastic Bulgarians who took an active part in the fight against the Ottoman rule. In 1868 Vassil Levski founded a revolutionary committee in Verigovo, 15 members of who took part in The Grand People’s Gathering at Oborishte. The village rose in rebellion against the Turkish rule in April 1876 together with other villages in the area, but it was devastated when the April Uprising was suppressed - the village was burnt down, many people were slaughtered, others sent on exile to Cyprus Island, some were driven away.

After the Liberation War, the place remained within Eastern Rumelia, but its potential as a health resort was recognized by the government even before the Unification. In 1942, the villages of Hisar and Momina Banya were merged, and the settlement received town status in 1964 under its modern name. Later, the nearby villages of Verigovo and Miromir were added to the town as outlying neighbourhoods in 1971.

Get in

By train Hisarya is the end point of a short branch line that splits off the Karlovo-Plovdiv line, which in turn is a secondary line that connects the Sub-Balkan Railway in the north and the main lines passing through Plovdiv in the south. This means that reaching Hisarya usually requires changing trains at the split-off station (Dolna Mahala), though at least there are multiple daily trains. As of summer 2026 there's a single daily direct train from Plovdiv, in the early morning. In any case, from either Karlovo or Plovdiv, the trip lasts 70-75 min including the change (if any). Both the station's sign and BDZ's website call the station just Hisar (Хисар).

By car Road 642 splits off from and then merges back into Road 64, which runs north-south and connects Karlovo and Plovdiv. In both cases, the exit is to the west side of Road 64. Hisarya is from Karlovo/Sopot and from Plovdiv.

Get around

Hisarya is a small, mostly flat town, and most of the points of interest are concentrated in a relatively small area. Public transport does exit - three bus lines connect the outlying neighborhoods to the central part of the town.

See

The ruins The walls of the Roman city encompass a roughly rectangular area, 630 by, approx. ; in places, they have been preserved up to a height of . The fortifications included 44 towers and four main gates, one for each cardinal direction, but only the southern and western gates are relatively well-preserved. In addition to the various ruins, the area within the walls contains a park with mineral water drinking fountains and a sizable modern residential area.

"Naked woman" fountain. A modern fountain with a statue of a nude woman, in the middle of a park. Immediately south of it there's a decorated colonnade (built 1960) with a mineral water drinking fountain hooked to the Momina Salza spring. Further along the alleys to the south there's another, smaller fountain with a boy with a ewer, and then the ruins of the Thermae.

Southern Gate. The southern gate of the fortress is the most imposing one and a symbol of Hisarya. The two "humps" at its top are the source of the nickname. Only the topmost part of the arch (between the "humps") is a restoration.

Momina Salza spring. The location of the mineral spring itself, with a drinking fountain on top. The name means literally "tear of a maiden", but it's also the Bulgarian name of the flower lily of the valley.

Roman Tomb. An underground Roman family tomb outside of the walls, open for visitors.

Sights, parks, mineral drinking fountains

Tourist Information Center. At the corner of the building it shares with the "Ivan Vazov" community center (chitalishte). There are a couple of amusing exhibits inside, including several kinds of hisarche ewers (хисарче, "little thing from Hisar(ya)"). These were decorative ceramic vessels for mineral water, made for the visitors of the resort - people would fill them from the springs to drink the water throughout their day, and then keep them as souvenirs. Unsurprisingly, the increased availability of plastic bottles ended that tradition. In front of the Center there's a small garden with benches, a fountain and a "giant" chess board; right across the street there's a selfie-friendly "HISARYA" sign at the corner of the Momina Banya Park.

Water-Drinking Pavilion. Another ornate mineral water drinking fountain with a small statue of a woman. Supplied from Borehole #3, contains radon.

Momina Banya spring (and park). The drinking fountain is in the middle of the park with the same name ("maiden's bath"), which should not be confused with the neighborhood to the north-east. In the park, there's a playground, an open-air gym, and a bust of Vasil Levski.

Verigovo cross and St. George Chapel. A large white cross on the small height overlooking the Verigovo Quarter (the part of Hisarya north of the railway station). There's also a chapel and a roofed picnic bench with a view of Verigovo and the rest of the town.

Momina Banya cross. A large white cross on the small height overlooking the Momina Banya Quarter (north-east of the central part of town, along Road 642/Hristo Botev Blvd). There's a small observation deck and picnic shelter with a fireplace.

Do

Fishing Pond - common carp, caracian carp, silver carp, catfish Motocross track

Bathing In addition to the hotels' spa and pool facilities (see below), there's also a number of standalone pools and baths.

Hiking Hisarya lies at the base of the south-eastern slopes/foothills of the Proper (Central) Sredna Gora range (Sashtinska Sredna Gora), on the west side of the gap separating the central range from Sarnena Gora (Eastern Sredna Gora). There are a couple of spots suitable for short hikes or picnics outside of Hisarya - the crosses mentioned in #See - but as they are used primarily by the locals, the footpaths leading to them are not particularly well marked and may not show up even in OpenStreetMap.

More serious hikes involve venturing deeper west into the woods of Sredna Gora, multi-hour stages and altitudes of more than above sea level, so prepare accordingly. The Communist-era hiking infrastructure in Sredna Gora has been in decline for decades, and few of the mountain huts remain in operation; the 2008 economic crisis and COVID-19 haven't been kind to modern enterprises either. Due to the inconsistent (or non-existent in the first place) trail markings, using a map and a GPS-enabled device is a must. Online map sources: OpenStreetMap and BGMountains.org (online map zoomed in on Fenera Peak; downloadable maps for Garmin with Latin place names). There's also a paper hiking map of Sredna Gora in 1:50,000 scale published by Domino in 2016 (red cover, title on yellow rectangles; allegedly in Bulgarian and English, but mostly in Bulgarian; information about any businesses is probably obsolete).

Eat

Garden Restaurant Chinar. Restaurant with additional seating area in a garden/yard across the street and some amusing decorations (early 20th century/pseudo Ancient Rome). "Chinar" means "plane tree" (Platanus orientalis).

Drink

The water from local mineral springs is bottled under the brand name ХИСАР (HISSAR).

Sleep

Being a resort town, Hisarya has a disproportionate number of hotels and other lodgings.
