Bozhenashki Urvich – Botevgrad is a medieval stone fortification, today an archaeological monument of national importance. The secrets of this old fortress began to come to life in 1918, when at the roots of the fallen after a storm centuries-old tree was discovered medieval rock inscription of Sebastos Ognyan.
According to archaeological research conducted in 1972, the place was inhabited as early as the prehistoric era, but the first fortress facilities date back to V-VI century as a unit of the early Byzantine defense system. Its heyday the fortress Bozeniki Urvich reached through the XIII-XIV c., when the outermost fortress wall was built, building from the north the only accessible place from Bozhenitsa.
Since 1966 the medieval fortress has been declared a site of national importance. In 1971 the first excavations of the expedition called “Sebastos Ognyan” started. It was carried out under the direction of Pavel Dishev and with the help of Vasil Dimitrov, Patriarch Velev (chief editor of the newspaper Botevgradski Flame) and architect Yordan Yordanov. The first discovered objects were ceramics and early Byzantine coins from Justin (518 – 527) and Justinian I (527 – 565), which show that the fortress was built in this period.
