The town is situated on the Haskovska River, in the Haskovo Highlands. Its southern sections are part of the low spurs of the Eastern Rhodope Mountains.
According to the archeologists, a settlement existed on the site of today's town as early as 7000 years ago, during the Neolithic Age. Numerous traces of habitation have been discovered from prehistoric, Thracian-Roman, late Antiquity and medieval times within the territory of the town and outside of it. In the 9th century, a fortress was built in Haskovo, which subsequently became a town during the First Bulgarian Kingdom - the centre of an important region between the Klokotnitsa, Harmanliyska and Maritsa rivers. Excavations and their study have provided much data about the history of Haskovo. In 1782, the town was mentioned in documents under the name of Marsa. The name by which it was widely known during the Ottoman period is Haskyoy (has - tur. clean and kyoy - tur. village). The settlement was also mentioned as Chistgrad (clean town) during the National Revival era. The mass movement of Bulgarians to live in Haskovo had already begun by the beginning of the 19th century. At that time the town maintained a lively trade with Odrin, Enos and Tsarigrad (Istanbul). It became famous for its cotton and silk fabrics and rugs. After the liberation of Haskovo from Ottoman rule at the beginning of 1878. the town's administrative, social and economic restructuring began. Mills, creameries, silk thread spinning workshops, and numerous tobacco warehouses appeared. New churches, schools, residential and administrative buildings were constructed. The beginning of the new, modern development of the town was set.
