The English monk and historian Bede mentions Abercorn as the site of a monastery and seat of Bishop Trumwine who was the only bishop of the Northumbrian see of the Picts. The monastery is now known to have existed close to the present day church. The church itself dates partially from the 12th century, although its most interesting features are the private aisles created for the three major families of the area, the Dalyells, the Hamiltons, and later the Hopes, who had their own enclosure behind the altar built by architect William Bruce. The Hope mausoleum, designed by William Burn, is located adjacent to the kirkyard. Older burial monuments include Norsemen 'hogback' stones, and fragments of 7th century Northumbrian crosses.
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.
