Kyustendil

 city, spa town

Kyustendil lies in the most Western part of Bulgaria, in the beautiful valley of Kyustendil, set on the banks of Banska River. It is situated on the Northern slopes of the Osogovo Mountain, at 525 m. altitude and has population of around 56000. Kyustendil lies ninety kilometers southwest of the capital Sofia, seventy km northwest of Blagoevgrad, and only twenty-two km northeast of the border with Macedonia. Kyustendil and its region are popular as the orchard of Bulgaria, where many fruits are grown. The town is also a well known spa resort of national importance and a regional center.
Kyustendil is well connected with the rest of the country by both bus and railway lines. There are regular buses to the capital Sofia, as well as to all neighboring towns such as Blagoevgrad, Dupnitsa, Pernik, etc.
Kyustendil is one of the most ancient towns in the country - the mineral waters in the area attracted Thracian tribes, as early as in 5th - 4th century B.C., when they have established a settlement in the region. Around the first century the Romans turned it into a fortress (known as Pautalia), a trade center, and a popular spa resort. The town was included to the Bulgarian State during the time of king Kaloian (1197 - 1207) and later in sixteenth century it was renamed to Kyustendil.
