The church's foundations were laid in 1680, and the first service was held in the building only days later, even though it was still without proper fittings. Baptisms, a wedding and a burial followed within the year, suggesting the church quickly became central to life at the ironworks. The building itself was not fully completed and consecrated until 1696. Erik Walltier, appointed in 1680, served as the community's first priest and also taught at the works school.
The timber-built church has a rectangular nave with a straight-ended chancel to the east, a sacristy attached to the north side, and a porch at the west end. Plain rectangular windows are set into the white-painted, standing board cladding of the exterior walls. During a Russian raid on Galtström in 1721 the works buildings were burned, but the church itself was spared.
Inside, the church is notable for its finely carved woodwork, attributed to the craftsman Jöns Olofsson and his son, from Attmar parish. Sources describe this decorative scheme as among the most cohesive of its kind among Västernorrland's works churches, and it is said to survive largely intact despite later renovation work, most recently in 1990.
Among the furnishings, a seventeenth-century-style pulpit stands in the church, along with a wooden cross and altarpiece at the east end. On the north wall hangs a painting of the Ascension of Christ, one of the oldest gifts to the church, bearing a dedication dated 1702; it is thought to have been donated by Johan Anton Parment, a Walloon-descended tenant who managed the ironworks between 1688 and 1703.
