Samuil’s Fortress is located nearby a mystical village called Klyuch (Key), adjacent to the border with Macedonia. This site relates to a tragic moment from the history of Bulgaria. In 1014 in the battle at Belasitsa with the Byzantine army, the Bulgarian’s suffered a great defeat after which 14 thousand survivors were blinded and released, leaving on every 100 one man with just one eye to lead them home. At the sight of this, the heart of Tsar Samuil stopped from the terror, thus ending both his life and the First Bulgarian Kingdom. The Bulgarian Kingdom was restored 180 years later with the rebel of Ivan Asen and his brother Petar.
