The chapel was originally built in 1660 to serve the fishing community at Agö harbour, and there is said to have been an earlier chapel further inland, though details of that structure are unclear. In 1831 the building underwent a thorough renovation and was extended eastwards, giving it the enlarged form seen today and making it the largest fisherman's chapel in Gävleborg.
Most of the interior fittings date from the early 1700s through to the 1800s. Among them is an altar ornament from 1832 featuring a gilded cross with a crown of thorns, and a chancel screen with pyramid decoration dated 1766. The pulpit now in use was made in 1771 by Jöns Dahlström of Hudiksvall and gilded by Paul Hallborg, replacing an earlier pulpit that had been brought from Hudiksvall church in 1671.
The chapel's bell has its own layered history: first cast in 1616, it was later recast and enlarged in 1762 by Erik Hillström of Gävle.
Outside stands the so-called "ljusstenen", or light stone, a sundial dated to 1680, a modest but distinctive survival from the chapel's early years.
According to the parish, the chapel continues to be used for a summer clergy weekend, as well as occasionally for baptisms and weddings, though visitors should not assume regular access on this basis.
