The Rock-hewn Churches of Ivanovo are an integral part of the large monastery complex called "St. Michael the Archangel," an exceptional spiritual and literary center of Bulgarian Medieval art. This complex was developed during the time of the second Bulgarian kingdom by church hermits. The 14th-century murals, rock-hewn churches, chapels, monasteries, monk's cells, and unique mural paintings in the style of the Tarnovo and Constantinople School (14th century) survived to this day, having weathered the vicissitudes of history.
