It is not known how or why the stone circle was constructed. Similar stone monuments exist across
Northern Europe and the
British Isles. Some of these have been excavated, and were found to be graves dating from the end of the
Bronze Age until the end of the early
Iron Age, dated to between 500 BC to 600 AD in
Scandinavia. In
Sweden there are a great number of similar circles called
Domarringar (judge circles). They often have an odd number of stones, usually 7, 9 or 11. Often they also have a larger stone to the east, and most are burial sites from the late Iron Age. There are also stone settings with elliptical shape and sharp edges, thus resembling a ship. There are also theories that their shape could be used as a calendar based on the position of the sun. One such is
Ale's Stones in
Scania. An excavation at Stoplesteinan during the 1930s found that the ground in the circle's center is paved with stones. Traces of burnt material were also found, lending credence to the theory that it is located at a place of burial.
Snorre says in his '
Heimskringla' from the 13th century about Norwegian history that
fyrsta öld er kölluð brunaöld; þá skyldi brenna alla dauða menn ok reisa eptir bautasteina (The first period is called the "burn age", since all dead men were burned and stone monuments raised for them). ==References==
