The idea of building a proper church for Skärhamn took shape in 1919, when a committee was formed to raise funds. Progress depended heavily on voluntary effort: a newly formed sewing circle raised substantial sums year after year, and many local people contributed unpaid labour. Building work began in earnest in 1929, and within three years the church was ready for consecration by Bishop Block on the second Sunday of Advent.
Designed by the architect Axel Forssén, the church has a white-painted timber exterior and a slate roof. It follows a simple single-nave plan with a narrower, rectangular chancel to the east, a sacristy to the north, and a west tower whose ground floor serves as the porch; a staircase leads from here up to the gallery. The tower is topped with a pyramid-shaped spire, and the nave and chancel are covered by a recessed, whitewashed barrel vault.
Inside, the wooden altar is carved with vine branches and grape clusters, beneath an altarpiece by the Gothenburg artist Gunnar Ström, painted at the time the church was built. It shows Christ on the cross flanked by two mourning women. The pulpit carries inscriptions drawn from the four Gospels, and the wooden font, fitted with a brass basin, stands beside a bronze three-armed candle holder.
Among the church's furnishings are two model boats and a votive ship, a type of offering traditionally given in thanksgiving for protection at sea, often by a sailor or fisherman who had survived danger. Skärhamn's example depicts the three-masted barque Carl of Göteborg and was donated in 1932 by the Gothenburg master builder Karl Hansson, a fitting tribute in a town with strong maritime ties. Outside the church, a memorial stone erected in 1956 commemorates local seamen lost at sea.
The church has an organ in the gallery, said to date from 1941 and rebuilt in 1971, though Wikipedia's account instead records a nine-stop organ built in the chancel in 1982 by Hammarbergs Orgelbyggeri — it is not clear from the available sources whether both instruments exist side by side or whether the accounts describe the same instrument differently. For most of its history the church belonged to the Skärhamn parish association, one of only two church-association-owned churches in Sweden, until it was given to the Church of Sweden in Tjörn in autumn 2022, coinciding with the building's 90th anniversary.
