The town of Devin is located in South-Central Bulgaria in Rhodopes mountain. It belongs to Smolyan district. The town is mostly famous for its mineral springs known from ancient times. This area was settled by the Thracians around 1400 B.C. Later, during the 17th century, many Christian Bulgarians in this area were cruelly forced to convert to Isliam. However, they keep their Bulgarian traditions and language alive to this day. Devin has several mineral water springs with a temperature between 37 and 44C. The water is clear, colourless, palatable, odourless, hyper- and homeo-thermal, mildly mineralized, and contains hydrocarbonates of sodium and small quantities of fluorine. The climate of the spa is transitionally continental, considerably tempered by the southern influence. The internationally famous year-round resort Pamporovo is situated 35 km away from Devin.
