The medieval church at Örsås was extended over the centuries and, according to one account, stood completed in 1818, only to suffer fungal damage that led to its replacement by a new grey stone church inaugurated in 1958 with seating for 700. However, the Wikipedia record gives a markedly different narrative: a decision to build a new church was taken in 1849, delayed by disputes over its location, with construction finally carried out in 1857 to 1858 by builders Peter Petterson and Andreas Persson, and consecration following in 1860. Visitors should be aware these two accounts of the building's recent history do not agree, and it has not been possible to reconcile them here.
The present stone church, built in a Neoclassical style, has a rectangular nave with a semicircular chancel to the east, an attached sacristy, and a west tower. Entrances are found on the west side of the tower and on the north and south sides of the nave. The tower is topped by an unusually tall, narrow, eight-sided white-painted lantern crowned with a gilded cross on an orb. Much of the interior dates from the time of construction.
The chancel windows, painted in 1931 to 1932 by the Borås artist John Hedæus and made by Stockholms glasmåleri, depict biblical figures, and Hedæus also painted the altarpiece installed at the same time, showing the Sermon on the Mount according to one source. The pulpit and altarpiece surround are thought to have been made around 1858 by Johannes Andersson of Mjöbäck. A hexagonal white-painted wooden font stands by the south side of the chancel.// Among the older furnishings are silver communion vessels donated in 1667, a carved and gilded wooden lamb once used as an altar ornament, and a wooden sculpture from the 1500s or 1600s depicting the entombment of Christ, connecting the present building to the church's much older origins.
Two bells hang in the tower, both bearing verse inscriptions; the smaller is said to have been cast in 1763. The organ was substantially rebuilt in 1957, when the number of stops was increased from eleven to twenty-two and a new Rückpositiv division was added behind the old façade pipework.
A 2015 renovation, noted in one source, created a chapel and kitchen beneath the gallery, adapting the building for continued parish use.
