About Aspö, Karlskrona#

Aspö is an island in the Blekinge archipelago that forms part of the Karlskrona naval harbour area in Blekinge County, Sweden. The island is known for its coastal fortress and for its close connection to the naval history of Karlskrona.

The principal visitor attraction is the Drottningskär Citadel, a historic coastal fortress built to defend the naval harbour; the island also offers walking routes, shoreline views and a small harbour village. The scale is that of a compact island community with historic military architecture rather than a large resort.

The citadel and surrounding naval facilities form elements of the wider Karlskrona maritime landscape that is inscribed as a UNESCO World Heritage site for its preserved naval base and town planning.

Aspö lies a short ferry crossing south of Karlskrona town centre in the Blekinge archipelago and is easily reached by the regular local ferry service.
