Stones of Mora was the place where the Swedish kings were elected. The origin of the tradition is unknown, but it has been known since the 13th century and mentioned by Snorri Sturlason (died 1241). The first known document tells that Magnus Ladulås was elected at the Stones of Mora in 1275. Magnus IV was elected at the stones on July 8, 1319 and Kristian I in 1457. He was the last to be elected at the stones.
The Stone of Mora and many stones which flanked it with inscriptions commemorating the elections of earlier kings, were probably destroyed in 1515 during the civil war against the Danes. Gustav Vasa and John III are said to have tried to reconstruct the Stones of Mora without success.
One of the fragments is known as the stone Three Crowns since it is the earliest known example of the use of Sweden's national symbol. The fragment is what remains of the election of Albert of Mecklenburg.
The building where the fragments are contained today was constructed by Carl Wijnbladh in 1770.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
