Kastelholm Castle
Kastelholm Castle is a medieval Swedish-built stronghold on Åland, Finland, first documented in 1388. The complex combines a rectangular stone keep, adjoining residential ranges and defensive walls, and served military and administrative roles; today it is a partially restored museum site. The castle originally stood on a small island protected by water-filled moats and retains visible ruins alongside restored buildings.

As it stood in 1560
The shape it held in its prime.
A compact cluster of thick, rough fieldstone ranges and a rectangular keep grouped behind a low curtain wall, with sections of red brick infill visible alongside pale, limewashed stone. Buildings rise to simple pitched roofs and small, deeply set rectangular windows with wooden shutters; one wing shows an exposed ruin with ragged masonry and missing upper walls. The ensemble sits on a raised grassy bank formerly surrounded by moats, with trees and a nearby fjord in the background.
