The Boyana Church, in the eponymous Sofia suburb at the foot of Mt. Vitosha, is one of the few complete and perfectly preserved mediaeval monuments testifying to the significant contribution of Bulgarian monumental painting to European culture in the Middle Ages.
Boyana Church consists of three buildings. The eastern church was built in the 10th century, then enlarged at the beginning of the 13th century by Sebastocrator Kaloyan, who ordered a second two storey building to be erected next to it. Later the architectural ensemble is completed by a third church, built at the beginning of the 19th century. This site is one of the most complete and perfectly preserved monuments of east European medieval art.
From an architectural point of view, Boyana Church is a pure example of a church with a Greek cross ground-plan with dome, richly decorated facades and decoration of ceramic elements. It is one of the most remarkable medieval monuments with especially fine wall paintings.
