The Abbey of the Santo Spirito (Holy Spirit), built by the Norman Count Ruggero and his wife Queen Adelasia in 1092–1098, was consecrated in 1153. It has been greatly altered in subsequent centuries. The original outlines are still identifiable to the rear, where its characteristic massive jutting apses can be seen. These are separated by flat pilasters and connected by a series of small arches. The left-hand entrance has an ogival portal from the 13th century. The lunette once contained a figure of Christ Blessing, which was eventually moved inside the Abbey. Notable are the rectangular nave and wooden-beamed ceiling. The walls and the apses have frescoes attributed to the 14th century. The vault of the apse shows a 17th-century figure of Christ Pantocrator.
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.
