Kyustendil is a town in the far west of Bulgaria, and the capital of the Kyustendil Province. The town is situated in the southern part of the Kyustendil Valley, near the borders of Serbia and the Republic of Macedonia; 90 km southwest of Sofia, 130 km
northeast of Skopje and 243 km north of Thessaloniki. During the Iron Age, a Thracian settlement was located within the town, later known as Roman Pautalia in the 1st century AD. In the Middle Ages, the town switched hands between the Byzantine Empire, Bulgaria
and Serbia, prior to Ottoman annexation in 1395. The town was liberated in 1878 from the Ottoman empire. It is named after Konstantin Dragaš, a 14th-century regional lord.
