For over 700 years Örebro Castle has kept a watchful eye on everyone crossing the bridge on the River Svartån. The oldest part of the castle, a defence tower, was erected in the latter half of the 13th century. This tower was added to in the 14th century to make a larger stronghold. The castle was expanded during the reign of the royal family Vasa between 1573-1627 to the impressive Renaissance castle.
After Vasa family Örebro castle was left to decay, but the main restoration took place in 1758-1764 by Carl Johan Crondstedt. After him the castle was used as a residence of county governor. The castle was finally restored to the 16th century appearance between 1897-1900.
Today there are guided tours, an exhibition centre and the castle is a very worthwhile sightseeing destination.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.
