Borgholm Castle

Borgholm Castle is a large castle ruin located in the town of Borgholm on the island of Öland, Sweden. The site has medieval origins and later served as a royal and noble residence before becoming the ruin seen today.

Visitors explore thick masonry walls, a central keep and open courtyards that create a dramatic ruinscape with views across the Kalmar Strait. Seasonal exhibitions interpret the site’s transformation from a medieval fortress to a later palace and its eventual destruction.

The site began as a medieval stronghold and was substantially rebuilt and enlarged over several centuries, including major Baroque-era alterations in the 17th and 18th centuries. The complex was largely gutted by fire in the early 19th century and was not rebuilt as a functioning palace.

The ruin sits in the coastal town of Borgholm on Öland’s west coast, facing the Swedish mainland across the Kalmar Strait; access to the island is normally via the Öland Bridge to Kalmar.

• Access: Öland is connected to the mainland by the Öland Bridge, a fixed link of about 6 kilometres to Kalmar that provides the usual vehicle access for visitors.
• Current condition: The castle was largely destroyed by fire in the early 19th century and has since remained a ruin, with parts accessible to visitors during the tourist season.
