Lindholmen Castle is a former Danish fortified castle on the banks of lake Börringe. It became an important fortification in the defence of Scania during the Middle Ages because of its strong encircling defensive walls and double moats. At the time, a small river and treacherous marshes made the terrain surrounding the castle hard to navigate. Originally a private castle, it was in 1339 turned over to Magnus Eriksson, king of Sweden, Norway and Scania.
In 1395, Margaret I of Denmark used the castle to conduct peace negotiations with the deposed king of Sweden, Albrecht von Mecklenburg, who had been forced to give up the Swedish throne in her favor. The meeting at Lindholmen to determine Albrecht's fate lasted 16 days and was attended by so many participants that tents had to be erected on the castle grounds to accommodate them. Before the negotiations in 1395, the Swedish king had been held prisoner in Lindholmen Castle for close to seven years. He was captured and taken there following his defeat at the battle of Falköping in 1389. During his imprisonment, the Danish queen was the de facto ruler of Sweden.
During the 15th century, the castle's importance waned. It was torn down in the 16th century in order to provide building material for Malmöhus Castle. When Scania became Swedish in 1658, Charles X Gustav gave Lindholmen estate, along with Börringe Abbey, to his son Gustaf Carlson. During the reduction, Lindholmen became crown property and was leased out. In 1723, Lindholmen and Börringe Abbey were bought by Erasmus Clefwe and in 1827 the joined estates were divided into smaller pieces and sold off.
Today a grassy mound is the only structural remainder of Lindholmen Castle.References:
Frösöstenen is the northern-most raised runestone in the world and Jämtland's only runestone. It originally stood at the tip of ferry terminal on the sound between the island of Frösön and Östersund. The stone dates to between 1030 and 1050. It has now been relocated to the lawn in front of the local county seat due to the construction of a new bridge, between 1969 and 1971, on the original site.
Frösö runestone inscription means: Austmaðr, Guðfastr's son, had this stone raised and this bridge built and Christianized Jämtland. Ásbjörn built the bridge. Trjónn and Steinn carved these runes.
