The scenic Kastelholm area is characterized by both history and vital innovation.

Here you will find Kastelholm Castle, dating back to the end of the 14th century, the open-air museum Jan Karlsgården, rich in the Ålandic building tradition, and the prison museum Vita Björn, with an extensive history in the prison system.

If you want to eat and drink well, or maybe try the Ålandic apple wine or Ålvados apple snaps, you can go to Smakbyn, which is run by the restaurateur Michael Björklund. For good coffee and pastry and freshly-baked bread, there is the café and bakery BAKA! at Tosarbyvägen 5.
At Jan Karlsgårdens Wärdshus , you can enjoy freshly-baked pastries, savoury sandwiches on sourdough bread, fresh salads and summery ice cream.

The two international-class golf courses of Ålands Golfklubb are on the other side of the sound. The golfing area also has a restaurant. If you visit Kastelholm in your own boat, the guest harbour, Kastelholms gästhamn, is right next to the castle.

Kastelholms gästhem, Klingbergs stugor, and Pengels stugor are available for anyone who wants to spend the night.

Kastelholm is located in Sunds kommun, a modern municipality rich in cultural heritage.


Today the old crown prison Vita Björn is a prison museum from a time when shackles and chains were a part of a prisoner’s everyday life. Visitors to the museum can learn about the development of prison management from 1750 until the 1950’s.


The Jan Karlsgården Open-air Museum is free to visitors and rife with Ålandic culture and traditions. Visitors will get an idea of what an Ålandic farm might have looked during the second half of the 1800’s. Many activities are also organized here, both during the summer and winter.
