The chapel was built in 1843 using timber donated by the city of Gävle, raised by the "housefathers" of the neighbouring fishing hamlets of Bönan and Utvalnäs. It is a simple rectangular timber building with a porch to the west and a small sacristy partitioned off in the south-east corner. The exterior is clad in white-painted panelling, with a tiled saddle roof, while inside the walls are lined with tongue-and-groove panelling beneath a flat ceiling that dips slightly at the sides. A modest bell tower was added in the churchyard during the 1870s.
Ownership passed to the city in 1892, and when Gävle parish was divided in 1916 the chapel came under the newly formed Heliga Trefaldighet parish. Ahead of its centenary, the building was renovated with an enlarged sacristy and porch, based on proposals by Sven Henrik Wranér, and it was reconsecrated in June 1943. The porch was extended again in 1972 to provide space for a vestment room.
Inside, the altar wall is decorated with a carved frame made by the fisherman Per Wickman at the time the chapel was built. Beside the altar stands a pulpit set against a painting of Christ. A font of red Gävle sandstone, designed by the city architect Sven Wranér, was installed in 1952. The chapel also has a small mechanical organ built in 1963 by the Magnusson firm of Gothenburg.
The chapel has a lighter footnote in popular culture: Mike Edwards, singer with the band Jesus Jones, is said to have married here.
