First monasteries appeared in Bulgarian at the times of the Christians persecution during the Roman Empire and with the adoption of Christianity as official religion in the ix century, the country witnessed a boom in the construction of monasteries.
In contrast to the quite austere Western Europe architecture, Bulgarian architecture created a colourful decorated style later adopted by Byzantine architecture and the architectural practices in Russia, Serbia and other Orthodox
religion states.
During the entire five centuries of Ottoman yoke (xiv-xix c.), the Orthodox Church and their monasteries acted as centres of patriotism that helped to national identity to survive taking also an active part in the revolutionary struggle for liberation.
Unfortunately, during the 5 centuries of Ottoman domination the majority of them were burnt down, during the National Revival period (xviii-xix c) they were rebuilt following mediaeval traditions to become nowadays outstanding architecture landmarks.
