Located on the outskirts of Sofia, 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. The frescoes in this second church, painted in 1259, make it one of the most important collections of medieval paintings. The 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.

Brief synthesis

There are several layers of wall paintings in the interior from the 11th, 13th, 15-17th and 19th centuries which testify to the high level of wall painting during the different periods. The paintings with the most outstanding artistic value are those from 13th century. Whilst they interpret the Byzantine canon, the images have a special spiritual expressiveness and vitality and are painted in harmonious proportions.

Integrity

The integrity of Boyana church is fully assured. In 1917 a park was created around the church, thereby securing its immediate surroundings through being separated from the impact of modern traffic. The property has also remained intact from historic invasions, and other destructive threats. Three separate zones are defined in the property boundaries and buffer zone, through which appropriate control measures are applied.

Authenticity

The concept, form and development of the three constructional phases of the property, from the 10th-11th; 13th; and 19th centuries, are clearly evident. Necessary conservation and restoration works have been completed. Where sufficient evidence existed, later façade renders have been removed to reveal the original appearance of walls.

To safeguard and present the internal 11th and 12th centuries fresco fragments, those from the 13th century, and the later 1882 additions in the antechamber, they were cleaned, refilled and conserved. This work was completed in 2008. The property is now air-conditioned, and under constant surveillance.
