Carn Ban is a Neolithic chambered tomb located on the Isle of Arran. It is considered as one of the most famous of the Neolithic long cairns of south-west Scotland. It is of a type found across south-west Scotland known as a Clyde cairn. It is trapezoidal in shape, with a semicircular forecourt at the upper northeast end. The forecourt has an entrance leading into a long chamber divided into compartments by cross-slabs, similar to the arrangement at Torrylin Cairn, about 3 miles to the southwest. The chamber of Carn Ban is 30 metres long and 18 metres broad. The tomb was excavated in the late 19th century, but the only finds were a flint flake, an unburnt fragment of human bone, and a pitchstone flake.References:
Varberg Fortress was built in 1287-1300 by count Jacob Nielsen as protection against his Danish king, who had declared him an outlaw after the murder of King Eric V of Denmark. Jacob had close connections with king Eric II of Norway and as a result got substantial Norwegian assistance with the construction. The fortress, as well as half the county, became Norwegian in 1305.
King Eric's grand daughter, Ingeborg Håkansdotter, inherited the area from her father, King Haakon V of Norway. She and her husband, Eric, Duke of Södermanland, established a semi-independent state out of their Norwegian, Swedish and Danish counties until the death of Erik. They spent considerable time at the fortress. Their son, King Magnus IV of Sweden (Magnus VII of Norway), spent much time at the fortress as well.
The fortress was augmented during the late 16th and early 17th century on order by King Christian IV of Denmark. However, after the Treaty of Brömsebro in 1645 the fortress became Swedish. It was used as a military installation until 1830 and as a prison from the end of the 17th Century until 1931.
It is currently used as a museum and bed and breakfast as well as private accommodation. The moat of the fortress is said to be inhabited by a small lake monster. In August 2006, a couple of witnesses claimed to have seen the monster emerge from the dark water and devour a duck. The creature is described as brown, hairless and with a 40 cm long tail.
