The Mên-an-Tol is a small formation of standing stones in Cornwall. It consists of three upright granite stones: a round stone with its middle holed out with two standing stones to each side, in front of and behind the hole. When seen at an angle from one side, the stones form a three-dimensional '101'.
The site probably dates from the late Neolithic-early Bronze Age (approx. 2500-1500 BC) as do the other stone circles in West Penwith, and was probably used for ritual and ceremonial purposes.
The two side stones are both about 1.2 metres high. The westernmost stone was moved and brought into a straight line with the other two stones sometime after 1815. The holed stone is roughly octagonal in outline. It is 1.3 metres wide and 1.1 metres high; the circular hole is 0.5 m in diameter. The only other holed stone in Cornwall of this type is the Tolvan holed stone which can be seen in a garden near Helston.
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.
