The Boyana Church is one of the most important and valuable antiquities of exceptional historical and artistic significance. It is situated at the foot of the mountain of Vitosha. The oldest part of the church dates back to the early 11th century. According to an original manuscript, in 1295 the two - store part of the church was built and the rest was added in the middle of the 19th century.

The most interesting part of the monument are the murals done in 1259. The frescoes are rich in tone. The artist skilfully combines the requirements of iconographical canons with real life. 89 scenes are depicted, containing 240 human images - a real art gallery of the 13th century. The portraits of the founder of the church - patron Kaloian and his wife Desislava and of prince Konstantin and his wife Irina are the supreme peak of the skill of the artist. The monument was included in the World Register of Historical and Natural Sites in 1979.
