Velingrad location The Conference will take place at hotel "Zdravets" (https://www.hotel-zdravets.com/)

Velingrad has many hotels and guest houses. Some hotels near the conference are:




Velingrad (Bulgarian: Велинград [ˈvɛlinɡrat]) is a town in Pazardzhik Province, Southern Bulgaria, located at the western end of Chepino Valley, part of the Rhodope Mountains. It is the administrative center of the homonymous Velingrad Municipality and one of the most popular Bulgarian balneological resorts.
Velingrad is situated at 750–850 m above sea level. Summers are warm and winters are cold. The average annual temperature is 10 °C, while the average July temperature is 19 °C. The annual duration of sunshine is about 2,000 hours. The relative air humidity ranges from 65 to 75%. Surrounded by age-old pine tree woods, the town favors abundant sunshine.
There are more than 90 mineral water springs with curative and preventive properties in and around the town. The mineral waters (from springs and wells) vary considerably in temperature, mineralization, radon, silicic acid and fluorine content, and are suitable for treatment of a wide range of diseases. 9000 litres of water per minute spring from the five thermal and mineral deposits in Ladzhene, Kamenitsa, Chepino, Rakitovo and Kostandovo. Together with the numerous mineral waters, Velingrad boasts another natural phenomenon as well — the Kleptuza, the biggest Karst spring in Bulgaria, with an average discharge of 1200 litres of ice-cold water per second.
The natural environment, mineral springs and favourable for the treatment of a number of diseases climatic features make Velingrad a tourist destination of Bulgarian and foreign citizens.[citation needed] On the territory of the city there are 3 sanatoriums, over 60 hotels, 140 restaurants and entertainment. 6 holiday complexes have been modernised, offering all types of balneological services. Public mineral baths have been improved and 22 outdoor and indoor mineral pools have been built.



National currency

Bulgarian lev (pl. leva). Coins with smaller denomination are called "stotinki" (100 stotinki = 1 lev). There are banknotes of 5, 10, 20, 50, 100 leva. and coins of 1, 2, 5, 10, 20 and 50 stotinki.
