The church interior is dark, as not much daylight enters the building. Some of the few sources of natural light are narrow circular windows along the roof, examples of
daylighting. It was supposed that the narrow apertures would prevent the entry of evil spirits. Three entrances are heavily adorned with foliage and snakes, and are only wide enough for one person to enter, supposedly preventing the entry of evil spirits alongside the churchgoers. The portals were originally painted green, red, black, and white. Most of the internal fittings have been removed. There is little in the building, apart from the row of benches that are installed along the wall inside the church in the ambulatory outside of the arcade and raised platform, a
soapstone font, an altar (with 17th-century
altarpiece), a 16th-century
lectern, and a 16th-century cupboard for storing altar vessels. After the
Reformation, when the church was converted for
Protestant worship,
pews, a
pulpit and other standard church furnishings were included, however these have been removed since the building has come under the protection of the '''' (The Society for the Preservation of Norwegian Ancient Monuments). The interior structure of the church is characterized by the twelve free-standing columns that support the nave's elevated central space. On the long side of the church there is a double interval between the second and third pillars, but with a half pillar resting on the lower bracing beam (the pier) which runs in between. The double interval provides free access from the south portal to the church's central compartment, which would otherwise have been obstructed by the middle bar. The tops of the poles are finished with grotesque, carved human and animal masks. The tie-bars are secured with braces in the form of St. Andrew's crosses with a sun - shaped center and carved leaf shapes along the arms. The crosses reappear in less ornate form as braces along the church walls. On the north and south sides of the nave, a total of eight windows let in small amounts of light, and at the top of the nave's west gable is a window of more recent date - probably from pre-Reformation times. On the south wall of the nave, the inauguration crosses are still on the inside of the wall. The interior choir walls and west portal have engraved figures and
runes, some of which date to the Middle Ages. One, among the commonest of runic graffiti, reads "
Ave Maria". An inscription by Þórir (Thor), written "in the evening at
St. Olav's Mass" blames the
pagan Norns for his problems; perhaps a residue of ancient beliefs, as these female beings were thought to rule the personal destinies of all in
Norse mythology and the
Poetic Edda. " and gallery arches above The medieval interior of the stave church is almost untouched, save for its restorations and repairs, though the medieval crucifix was removed after the Reformation. The original wooden floor and the benches that run along the walls of the nave are largely intact, together with a medieval stone altar and a box-shaped baptismal font in soapstone. The pulpit is from the period 1550–1570 and the altarpiece dates from 1654, while the frame around the tablet is dated to 1620. The painting on the altarpiece shows the crucifixion in the centre, flanked by the Virgin Mary on the left and John the Baptist on the right. In the tympanum field, a white dove hovers on a blue background. Below the painting is an inscription with golden letters on a black background. A sacrament from the period 1550–1570 in the same style as the pulpit is also preserved. A restoration of the building was carried out in the early 1870s, led by the architect Christian Christie, who removed benches, a second-floor gallery with seating, a ceiling over the chancel, and various windows including two large windows on the north and south sides. As the goal was to return the church to pre-Reformation condition, all post-Reformation interior paintwork was also removed. Images from the 1990s show deer antlers hung on the lower, east-facing pillars. A local story claims that this is all that remains of a whole stuffed reindeer, shot when it tried to enter during a Mass. A travelogue from 1668 claims that a reindeer was shot during a sermon "when it marched like a wizard in front of the other animal carcasses". == Bell tower ==
