A place of worship has stood on this island for close to a thousand years, beginning most likely with a simple timber church. Nearby Hellberg's name hints that the site may have held pre-Christian significance before Christianity arrived, and a runestone by the church tower is considered the parish's earliest Christian memorial.
A stone church built in the 1200s served the growing parish for centuries, gradually extended and eventually reshaped into a cross-church with two transepts, completed in 1748, complete with a new organ and pulpit. Within a few decades this too proved too small for a population that had grown to roughly 3,400, and by 1832 it was decided to demolish it in favour of a much larger building.
The present church, designed by architect Carl Gustaf Blom-Carlsson, was built between 1832 and 1838. Because of its considerable size, around 59 by 27.5 metres, it had to be sited along the ridge of the island in a north–south direction rather than the traditional east–west alignment. When completed it seated an extraordinary 2,400 worshippers, making it one of the largest churches in the country at the time. It was consecrated on 21 July 1838 by Archbishop Johan Olof Wallin, who wrote a prayer for the occasion that later entered the Swedish hymn book as hymn 512, known locally as the Järvsö hymn.//
Cracks later appeared in the walls, and in 1892 the building was reinforced with twelve columns, transforming it internally from an open hall church into a three-aisled basilica. This alteration reduced the seating to around 1,700; further changes since, including widened aisles, have brought the number of fixed seats down to just over 1,400 today.
Inside, look for the pulpit carved by Magnus Granlund in 1772, rescued from the earlier church, briefly removed in 1892, sold for a single krona, then generously returned to the parish in 1936 before being restored and reinstalled during the 1958 renovation. The altar apse contains niches with marble-stucco figures of Christ and the apostles, the work of sculptor Yngve Andersson with Giovanni Inganni, while the font of white Italian marble was designed by Maj Starck and dedicated in 1970. A medieval fragmentary crucifix from the 14th century also survives among the church's artworks.
The church has two organs, both built by Grönlunds Orgelbyggeri: a larger organ on the gallery from 1993, incorporating an older 18th-century case, and a smaller choir organ from 1974. According to one source, singer Lill-Babs was buried here in 2018.
