Nykopingshus
The ruin and surviving tower of the castle where the Nykoping banquet of 1317 ended with two dukes starved in the cellar.
Updated 30 August 2026
The castle guarded the river mouth from the twelfth century and grew into a royal residence, and what it is remembered for happened in December 1317, when King Birger invited his brothers Erik and Valdemar to a Christmas banquet, had them seized in the night and left in the cellar, where they died. Most of the building burned in 1665 and was not rebuilt; the Kungstornet, the king's tower, survived and holds the museum, with the foundations and outer walls standing around it. The exhibitions cover the banquet, the castle's Vasa period and the region generally. It sits in a park in the middle of Nykoping and is free to walk around.
What you'll find
- The Kungstornet - the surviving tower, now the museum.
