At the foot of Stara Planina, 15 kilometers southeast of Knjaževac, in the village of Donja Kamenica, on the left bank of the Trgoviški Timok, an unknown landowner built the Church of the Blessed Virgin Mary at the beginning of the 14th century.
Today, it is a cultural asset of Serbia and the most valuable monument of the Diocese of Timočka. The church was built in the Moravian-Byzantine style with elements of Romanesque architecture. Some of the frescoes are unique in Serbian medieval painting. A special treasure of the Church of the Virgin is the foundational compositions and portraits of lords with rich details in the depiction of their clothing.
Also significant are the cycles from the life of Saint Petka in the south and north towers, as well as the frescoes: “The Last Supper”, “The Assumption of the Blessed Virgin Mary”, “Annunciation” and the embracing holy warriors Theodore Tiron and Theodore Stratilatus on horses.
