The origins of the Alfter palace go back to the 12th century. After it was destroyed many times and each time rebuilt provisionally, in 1721 the castle site was converted into a Baroque palace. The two-floor manor flanked by towers was largely based on the style of the previous buildings, but a lower castle with wings was added. The office of the Elector of Cologne's hereditary Marshall has been associated with Schloss Alfter since 1188. In 1445 the site came under the ownership of the Count and later Elector zu Salm-Reifferscheidt-Dyck.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.
