The Giant's Ring is a henge monument at Ballynahatty, near Shaw's Bridge, Belfast. It dates from the Neolithic period and was built around 2700 BCE. It is near the Shaw's Bridge crossing of the River Lagan, a point which has been used as a crossing of the river since at least the Stone Age. The original purpose of the monument was most likely as a meeting place or as a memorial to the dead.
The site consists of a circular enclosure, 180 m in diameter and 2.8 hectares in area, surrounded by a circular earthwork bank 3.5m high. At least three of the five irregularly spaced gaps in the bank are intentional and possibly original. East of the centre of the enclosure is a small passage tomb with a vestigial passage facing west. There were reports of other tombs outside the enclosure, but there is no trace of these.
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.
