Sparrsätra kyrka

The church's oldest surviving part is the sacristy, thought to have been built in the 1200s beside an earlier wooden church, of which no structural trace remains. Around 1300 the present stone nave was raised alongside this older sacristy. A porch was added in the first half of the 1400s, and the sacristy was extended northwards later that century. Towards the end of the 1400s the nave ceiling received its star vaulting, and work began on a west tower that was never completed; by around 1500 the unfinished tower space had simply been absorbed into the nave itself.

The building's grey stone walls, patterned with brick in the gable ends, are covered by a single shingle-clad saddle roof running over both the nave and the narrower western section. Further changes followed over the centuries: the roof was rebuilt in the 1740s, the windows were enlarged and altered in the 1750s, and a new west entrance was cut in the 1760s. A significant restoration in 1914–1915, led by architect Georg A. Nilsson, reordered the gallery, added Art Nouveau-style open pews, and uncovered Renaissance-style wall paintings in the south wall. A further restoration in the early 1980s revealed medieval wall paintings in the sacristy.

Among the furnishings, a two-part sandstone font from the second half of the 1100s is the oldest surviving object, its silver basin a later gift from 1968. A wooden processional crucifix from around 1300, found during the 1914–1915 restoration, now serves as an altar ornament. The finely carved pulpit, made in 1654 by the woodcarver Hans Hebel, was replaced in 1837 but reinstated during the early twentieth-century restoration.

Other notable pieces include a gilded silver communion chalice and paten from the late 1300s, still associated with the church, and a bronze incense burner from the late 1400s, now held by Enköping museum rather than in the church itself. Four brass or bronze chandeliers, acquired between 1663 and 1742, and a wooden poor box from 1760 add further texture to the interior.

Beside the church stands a wooden bell tower, probably erected at the end of the 1700s, replacing an earlier structure shown in an eighteenth-century drawing standing on the church's north side. It houses two bells recast in 1741 by the bell-founder Isaac Rockman.

The church has had a succession of organs since a small positive organ was recorded in 1642. The current instrument dates from 1915, built by E A Setterquist & Son of Örebro, with later adjustments in 1971 and a reconstruction in 1985.
