Built on the site of the ancient
town of Pautalia, is one of the most famous Bulgarian resorts.
It lies at the foot of Ossogovo Mountain at an altitude of
510-530 m. Thanks to the lush vegetation of the surrounding
landscape and the beautiful gardens of its neat lovely houses,
the town is refreshingly green and inviting.
The climate is traditionally
continental with Mediterranean influence. The mild weather
is largely due to the beneficial effect of the mountains which
surround the plain from the north, east and west. The average
annual temperature is 11C; and the average July temperature,
21.6C. The annual duration of sunshine is 2,200 hours on the
average , and the relative air humidity, 68 per cent.
The mineral waters of the numerous
fountains (natural springs and wells) have an almost uniform
chemical composition, temperature and sulphide content (71-73C;
9.4-11.3 mg oxidable sulphur compounds estimated in terms
of hydrogen sulphide). The waters are clear , colourless,
with a pleasant taste and a slight smell of hydrogen sulphide.
They are mildly mineralized, hyperthermal and contain sulphides,
silicon (83 to 104 mg of metasilicic acid), fluorine (7.6-8.9
mg per litre) and sulphates of sodium with a strong alkaline
reaction (pH 9.13-9.80). The total flow is about 2,400 l/min.
Their curative and preventive properties are mainly due to
the sulphides , the high metasilicic acid content, the high
temperature, the hypotonic effect, the mild mineralization
and the relatively high fluorine content.
The curative properties of
Kiustendil's mineral waters have been known since ancient
times. Another important curative agent, used for the systematic
treatment of a wide range of diseases, is the peat mined near
the village of Baikal which is reach in humic acids and organic
substances. It is used in peat baths, for general and partial
applications, vaginal and rectal electrophoresis, etc. The
favourite climate, the curative peat from Baikal, the mineral
waters and the possibilities of specific fruit-diet therapy
attract many Bulgarian and foreign visitors to Kiustendil.
