Lindholmen Castle, Medieval castle site on Slottsberget, Lindholmen, Gothenburg, Sweden

Lindholmen Castle stood on the rocky outcrop of Slottsberget on the former island of Lindholmen, now part of Hisingen in Gothenburg, overlooking the Göta Älv. No standing ruins remain: the last wall fragments were destroyed in 1875 when the Lindholmen shipyard built workers' housing on the hill. The hill is still covered with houses.

Lindholmen Castle is first attested in 1333, when King Magnus IV Eriksson dated a letter 'in castro nostro Lindholm'. It is probably not the place 'við Lindhólmana' in Hákonar saga, and it is absent from a 1315 document, so it was likely built early in Magnus's reign. In 1335 Magnus married Blanche of Namur at Bohus and gave her Lindholmen Castle, Lödöse and Värmland as her morning gift. After 1339 the castle disappears from written records; by 1410 it was uninhabitable, and in 1875 the last wall fragments were destroyed when the Lindholmen shipyard built workers' housing on Slottsberget.

The name Lindholmen comes from the linden trees of the former island, and the castle hill is still called Slottsberget, "the Castle Hill". Queen Blanche of Namur received Lindholmens slott, Lödöse and its bailiwicks, Värmland and Dalsland as her morning gift in 1335. The hill is now covered with workers' housing built by the Lindholmen shipyard in 1875, whose views over the Göta Älv make them sought-after.

The castle site lies on Slottsberget, the hill on Lindholmen in Gothenburg, where workers' housing was built by the shipyard in 1875. The hill is now covered with houses and offers views over the Göta Älv; the medieval remains themselves were destroyed during that construction.

The castle stood on a rocky outcrop still called Slottsberget, "The Castle Hill". The channel that once separated Lindholmen from Hisingen was known as Kvillen, and its remnant is today's Sannegårdshamnen; the channel survived until at least 1864.
