As it stood in 1764
The shape it held in its prime.
Low, elongated seafortress on a rocky skerry at the mouth of a bay, defined by continuous stone curtain walls and angular bastion platforms at the ends. Behind the ramparts sit several long, rectangular barrack blocks with low pitched roofs aligned parallel to the shoreline. Quays and short slips connect the island to small craft. Stone is locally grey and roughly dressed; roof coverings are pitched and tiled. The overall silhouette is horizontal and compact with stepped ramparts facing the sea.
Its story
The story of Svartholm Fortress.
Svartholm was built between 1749 and 1764 by Augustin Ehrensvärd on a small rocky island at the mouth of the Bay of Loviisa in southern Finland. Together with the planned land fortress at Loviisa, the sea fortress was intended to prevent invading Russian forces from entering what was then Swedish territory.
It served as a coastal defensive fortification, later passing through Russian occupation and partial demolition in the 19th century before modern restoration.
