Kullerstads kyrka

The church consists of a whitewashed nave and narrower, straight-ended chancel, both roofed with simple gables, with a later timber porch to the west and a sacristy added north of the chancel. It has no tower; instead a sturdy timber bell-frame stands in the churchyard, holding two bells. Sources agree the stone church dates from the early 1200s, though older suggestions of a preceding wooden church on the site remain unconfirmed speculation rather than established fact.

Inside, star-vaulted ceilings with rib-like mouldings cover both nave and chancel. Traces of medieval limewash paintings survive around the chancel arch, while later, more extensive decoration from the 1500s and the 1917 restoration was uncovered from beneath old plaster. The stone font, carved in the 13th century with leaf and mask motifs and a drainage hole for baptismal water, is counted among the church's oldest surviving furnishings. The mid-17th-century pulpit, dated by inscriptions to 1657 and 1658, stands near the chancel arch and carries carved figures of Christ and the four evangelists.

The chancel window holds a striking 1954 stained-glass design by the artist Brita Reich-Eriksson: a large red tulip against a blue ground, inspired by a biblical verse from the Book of Job reflecting on the brevity of human life. The stone altar table may also date from the medieval period. A carved wooden crucifix, given to the church in the 1920s, stands on the altar.//The church's organ history includes an early 18th-century instrument, a 19th-century rebuild, and further 20th-century work, culminating in a mechanical organ installed in the 1970s.

Beneath the chancel floor lies a vault of the noble Rosenstråle family, and several carved gravestones and funerary hatchments — ceremonial arms once carried in noble funeral processions — are preserved in the church, along with a 1622 memorial tablet to a former vicar and his family. Outside, at the entrance, a rune stone said to date from the 11th century was rediscovered built into the churchyard wall in 1969; local tradition holds that further inscribed stones may remain hidden there, though this is unconfirmed.

The churchyard itself shows two distinct phases: an older burial ground close to the church, later extended southward, and a separate woodland cemetery laid out in 1926, one of Sweden's earlier examples of this naturalistic style of burial ground, following the pioneering Ravenåsen cemetery in Karlskoga from 1905. Its informal planting, a small pond and waterfall, and a memorial grove reflect changing 20th-century attitudes to death and burial. Iron Age graves have also been identified nearby, marked with information signs.
