St Catherine's Church is the oldest church in Gdańsk. The first record dates from 1185, when Prince Sobieslaw I built a wooden church. It was replaced with a stone church in 1227-1239. St. Catherine’s church evolved over centuries and only reached its final shape in the mid-15th century. It was a Protestant church from 1545 until 1945, after which it became a Roman Catholic church. There are several magnificent details in the church, like Anton Möller’s triptych painted in 1563-1611.
The tower was destroyed in 1945 in World War II, but rebuilt again in the following decades. Today the church hosts a Tower Clock Museum.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.
