Styrsö, Island in Gothenburg archipelago, Sweden

Styrsö is an island in the Southern Gothenburg Archipelago, covering 3.86 km² with 1,341 residents (2020). It has four settlements: Byn, the church village with a 1752 church; Tången, a dense fishing village; Halsvik, where sea captains built villas; and Bratten, with summer houses and a guest harbour. A bridge connects Styrsö to Donsö.

Byn, one of the settlements, features a church from 1752 and traditional farms that retain their original structure from earlier centuries. This community shows how residents combined agriculture and fishing over a long period of time.

Tången grew as a separate islet where houses stood close together, as in other Bohuslän fishing communities. The trawlers that crowded the old harbour moved to Sandvik in 1960, where traditional fishing methods continue. The name Tången means seaweed.

The island is accessible through three ferry terminals at Bratten, Tangen, and Skäret and operates without private cars. Motorized transport like utility mopeds and golf carts are used for movement around the island.

Stora Rös, the archipelago's highest point, is a Bronze Age cairn on Styrsö's southern part. On clear days the view reaches Bohuslän to the north, Gothenburg to the east, Halland to the south and the silhouette of Vinga to the west. Below at Brännholmsviken lie the Vikingakyrkogården and a Bronze Age settlement.
