The present building of Nysted Church dates back to c. 1300. Originally it consisted of a central nave with a three sided apse to the east. The impressive tower was built a century later. In 1643 a spire was added, and in 1935 this was covered by copper. The Raben-Levtzau family of Aalholm Castle had their own chapel built in 1782. According a rumour there is a secret underground passage from the castle to the church. It hasn't been however found. The church was thoroughly renovated in 1864.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.
