The idea for a chapel on Olmen was raised in 1949 by Harry Freyschuss, then vicar of Hälsingtuna. Local fishermen and summer visitors on the island helped with the construction, which used timber felled on Olmen itself. Builder Gustav Westner erected the chapel to drawings by works foreman Fredrik Forslund, and it was consecrated on 4 August 1956 by Archbishop Yngve Brilioth.
The chapel is a simple timber building with an entrance to the west, a nave and a sacristy to the east. Its exterior is clad in wood panelling painted a pale grey, with a tiled roof crowned by decorative spires made by the smith Johan Johansson. An iron bell tower stands at the west gable, holding a bell that is said to be an old sawmill bell, a gift from Iggesunds bruk.
Inside, the chapel has a panelled ceiling and walls, also in light grey timber, giving the interior a plain, restrained character. The furnishings are simple and largely date from the same period as the building itself.
Among the chapel's fittings is a font with a silver bowl, said to have been donated, like the bell, by companies in Hudiksvall. A small metal model of a Viking ship hangs from the ceiling as a votive ship, a traditional maritime symbol found in many coastal churches in the region.
