Main image

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.

  • Ferry access and duration: Regular short ferry crossing from Karlskrona town centre takes about 10 minutes, making the island a common day-trip destination for visitors to Karlskrona.

What to See #

  • Drottningskär Citadel: Drottningskär Citadel, a 17th-century coastal fortress located on the island that is part of the Karlskrona naval defence system and included in the Karlskrona UNESCO World Heritage area.
  • Harbour and village: Small harbour and ferry landing that links the island to Karlskrona town with short seasonal crossings and a compact village of houses and maritime facilities.
