Boyana Church is a medieval Bulgarian Orthodox church situated on the outskirts of Sofia. In 1979, the building was added to the UNESCO World Heritage List.
Boyana Church was built in three stages: in the late 10th to early 11th, the mid-13th, and the mid-19th centuries. The oldest section (the eastern church) is a small one-apse cross-vaulted church with inbuilt cruciform supports. It was built in the late 10th or the early 11th century.
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.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
