Sund in three films: Kastelholm, its museums and Bomarsund
Three different ways to see Sund: a visit to Kastelholm and Vita Björn, an aerial view of the medieval castle and a drone flight over Bomarsund's fortress ruins.
The Rustic Wanderer frames Kastelholm as a stop on a cycling journey and visits both the castle and the nearby Vita Björn prison museum. That first-person approach is useful for imagining how the heritage sites fit into one outing, rather than as isolated entries in a guidebook. Treat it as a traveler's visit, not as an authority for historical dates or today's opening hours; those details change and belong to the museum's current visitor information.
