The present hall church, built of hewn sandstone with finely cut limestone detailing, has a three-aisled nave, a narrower straight-ended chancel, and a west tower. Most of the structure dates from the mid-13th century, though excavations during 20th-century restoration work revealed foundations of an earlier, smaller tower beneath the current one, and sandstone relief fragments from 12th-century tomb chests are built into the south nave wall, hinting at an earlier stone church on the site.
The tower has a dramatic history of destruction and rebuilding. Added around the mid-14th century, it reached about 75 metres, reportedly making it Gotland's tallest church tower. It was renovated in the 1730s but blew down in a storm in 1736; rebuilt again, its upper section was destroyed by a lightning strike in 1817. The tower seen today dates from 1820, when the lantern and the massive buttressing walls now supporting it were added, a change that also led to the tower's south portal being blocked, though its surround can still be traced from inside.
Inside, the nave is covered by nine vaulted bays carried on four round pillars, with an eye-catching alternation of red and grey limestone in the pillars, chancel arch and window surrounds, complemented by painted quadre decoration in yellow and grey. Wall paintings survive from both the 13th and 14th centuries; a figure scene on the north wall, dated to the mid-13th century, depicts the weighing of the soul of Emperor Henry. Later vault paintings from around 1700 were heavily restored around 1900, when the chancel's medieval-style stained glass was also added.
A notable survival is the trefoil-shaped opening in the chancel arch wall, said to be the only preserved medieval ambo, or stone pulpit, on Gotland. The font belongs to the so-called Byzantios group and dates from the second half of the 12th century, while the altar's sandstone table is topped by a large carved limestone slab. The carved altarpiece, from the 14th century, shows the crucifixion with Mary, John and the apostles, and a 1600s pulpit later replaced the medieval ambo as the church's main preaching stand. A modern limestone sculpture of Mary and the infant Christ, made by Sven Lundqvist in 1971, brings the collection into the 20th century.
The church has had several organs. Its first, built in 1840, was replaced by a Rieger instrument in 1932, itself rebuilt in the 1960s; the current mechanical organ was built in 1985, retaining the case front from the 1840 instrument.
