The church began as a simple hall-like building without stone vaulting. In the early 13th century it was enlarged with vaulting supported on columns and given a tower, whose portal is said to echo the west portal of Visby's St Mary's Cathedral. Around 1300 a more substantial rebuilding added the Gothic chancel and its portal, with the nave adapted to match.
The medieval wall paintings that once decorated the interior have not survived, but the unusual stained glass in the chancel window dates from the time of construction, as do the painted scenes of the Annunciation on the inside of the sacrament cupboard doors.
Among the notable furnishings are wooden sculptures from the period of the chancel's construction, originally part of an altarpiece: a figure of the risen Christ, a pair of apostles, and a figure said to represent Saint Catherine of Alexandria, though a restoration in 1752 altered this figure into a male form. The triumphal crucifix, in a north French style, is thought to be the work of the same master who carved the well-known Viklau Madonna. The font, decorated with scenes from the childhood of Christ, dates from the same era. The pulpit, from 1586 though later repainted, is said to be the oldest on Gotland, while the altarpiece was made in 1759 by a joiner and a painter working together.
A more unusual pair of items are two collection bags from 1775, made of red morocco leather with embroidery worked in Constantinople, presented to the church by the son of a former vicar who served as a chaplain there. A painting of Christ by the Gotland artist Folke Jupiter also hangs in the church.
The organ has been rebuilt more than once, with a mechanical instrument installed in 1971 replacing an earlier organ from the 1890s. Sources also mention a renovation of the church interior said to have concluded with a reopening in spring 2026, though this detail could not be independently confirmed.
