The Ring Of Brodgar Stone Circle And Henge, which is part of The Heart of Neolithic Orkney World Heritage Site, is a spectacular stone circle. The ring is surrounded by a large circular ditch or henge. The truly circular layout of the ring is an unusual attribute that singles it out as one of the largest and finest stone circles in the British Isles. The Ring of Brodgar (alternative spelling Brogar) comprises a massive ceremonial enclosure and stone circle probably dating from between 2500 and 2000 BC. Around it are at least 13 prehistoric burial mounds and a stone setting (2500-1500 BC). The erecting of the stones, along with the massive rock cut ditch was an activity that required considerable manpower and organisation.
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.
