About Kastelholms slott
Kastelholm is in Sund, outside the urban area of Mariehamn. The castle features stone wings, courtyards and levels built in different phases. Its position near the water helps explain access to the complex before the roads used for travel today.
The interior route allows you to observe the organization of spaces and the thickness of the structures. Nearby, the open-air museum Jan Karlsgården gathers traditional buildings, and Vita Björn presents an old prison. These visits have their own schedules and can extend the time spent in Sund.
Castle visits are concentrated from May to September, with other dates possible according to the calendar. Confirm opening times and transport before leaving Mariehamn. Combine Kastelholm with Bomarsund on a road day, allowing time to see both places without rushing.
