The Callanish Stones are an arrangement of standing stones placed in a cruciform pattern with a central stone circle. They were erected in the late Neolithic era, and were a focus for ritual activity during the Bronze Age. Archaeological excavation in the 1980s proved that the main circle was erected 4,500-5,000 years ago, and the chambered tomb a few generations later. The setting has a unique arrangement, with lines of stones radiating in four directions from the ring. It is not fully clear whether the stone alignments were constructed at the same time as the ring, or later. The layout of the site, along with many others across the British Isles, appears to have an association with astronomical events, the precise nature of which cannot be determined.
Numerous other ritual sites lie within a few kilometres. These are mainly more modest rings of standing stones, or single monoliths. The most impressive Cnoc Ceann a' Ghàrraidh and Cnoc Fhillibhir Bheag lie just over a kilometre south-east of the main Calanais ring, and originally consisted of rings of stones at least eight in number.
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.
