Utklippan lighthouse, Maritime navigation structure on Utklippan archipelago, Sweden.

Utklippan lighthouse is a navigation structure in the archipelago near Karlskrona, featuring a red conical skeletal tower with a central cylinder rising 30 meters above the Baltic Sea, topped with a grey lantern dome mounted on a white fortress base. The building stands on an isolated island group formed by Södraskär and Norraskär, accessible only by boat.

Utklippan has had a light station since 1789, when a basket light was used. The 1840 tower combined lighthouse and fortification; the present 30.9-metre Heidenstam tower was built in 1870 to Albert Theodor Gellerstedt's drawings. The flame burned colza oil until a kerosene lamp replaced it in 1887, and the station was electrified in 1948. The tower was automated in 1972 and the white main light was switched off in 2008, leaving a small passing light.

The name Utklippan means "outer rock" in Swedish, and the light station has been a landmark for sailors since 1789. The islands are a nature reserve, and the lighthouse is a state building monument. The Karlskrona Ornithological Club has run a bird-ringing station here since 1964, and by 2004 had ringed 319,504 birds of 194 species.

Visiting requires boat transportation since the islands are surrounded by water and have no road access. Arrange your passage with local boat operators or tour services that specialize in trips to this remote location.

Bird ringing at Utklippan began on a small scale in 1964, after the lighthouse was decommissioned in 1972 the Karlskrona Ornithological Club rented one of the keepers' houses. By 2004, 319,504 birds of 194 species had been ringed here. The island group also shelters the threatened green-spotted toad; in 1994 about ten males and a hundred young were released after only females remained.
