The Rock-Hewn Churches near the village of Ivanovo, Ruse Province, are a part of the UNESCO World Heritage List since 1979. The site was a curious source of attraction for Christian spirituality in the times of the Second Bulgarian Empire (12th – 14th centuries). The St. Archangel Michael Rock-Hewn Monastery consists of several complexes with impressive preserved murals. In the Saint Mary Church one can see the donors Tsar Ivan Alexander and his wife Tsaritsa Theodora depicted in full length.
