The church's earliest parts are thought to date to the 1250s, when monks from the Cistercian abbey of Ås, near the mouth of the River Viska, built a chapel here for lay workers on the abbey's land who needed somewhere nearby to observe the daily hours of prayer. This chapel was gradually extended, eventually becoming the present church, and its remains are believed to survive within the western part of the building.
The church is built of stone, now whitewashed, with walls over a metre thick. Its most visible later addition is the timber west tower, added in 1772 with a distinctive spire, replacing an earlier freestanding bell frame. The chancel was extended eastwards in 1791, giving the building its current three-sided east end.
Inside, the layout still reflects its Catholic origins, with a chancel arch that once created a clear separation between priest and congregation. Two carved wooden sculptures from the later 13th century, depicting St Olof and the Virgin Mary with the infant Christ, survive from this early period, along with a limestone font imported from Gotland, also thought to date from the 1200s.
The 18th century brought a change in mood, with decorative ceiling paintings added in 1723 and extended in the 1790s, featuring the Hebrew name of God at the centre and Latin-inscribed medallions of Christian virtues at the sides. A carved altarpiece and a pulpit with baldachin, dated 1679, also belong to this more ornate phase of the church's life.//During the 19th century, fashion turned towards greater plainness: the painted ceiling was boarded over, the carved altarpiece and pulpit were removed, and a painting of the Ascension took the altarpiece's place. Sources differ slightly on the exact sequence of these changes, but agree that a major refurbishment took place around 1880.
A restoration in 1950–1951 uncovered and repaired the hidden ceiling paintings and reinstated much of the 18th-century decorative scheme, and further work followed in 2008–2009. The church's bells and organ have also been renewed and altered more than once over the centuries, reflecting the building's continual adaptation to the tastes and needs of each era.
