Berkovitsa is a town and ski resort in northwestern Bulgaria. It is the administrative centre of the homonymous Berkovitsa Municipality, Montana Province and is close to the town of Varshets. As of December 2009, it has a population of 13,917 inhabitants.
Berkovitsa is situated on the northern slope of Kom Peak of the Berkovska Stara Planina Mountain along the valley of the Berkovitsa River, which is a tributary to the Barziya River, at an altitude above sea level 405 m. The town was mentioned for the first time in Ottoman documents of 1488. It is near the site of an old fortified settlement on the road from Sofia to Lom. The remains of the fortress and a church were discovered on high ground at Kaleto, just to the west of the present-day town. The former settlement was known as early as the reign of King Kaloyan and was mentioned as a border settlement in the period of the Vidin Kingdom.
