Västerlösa kyrka

A carved stone slab, once covering a chest-shaped grave of Eskilstuna type, testifies to the site's early Christian use. Its runic inscription records that Stenlög had the stone raised over his son Alver, asking God and God's mother to help his soul; the stone, now known as Östergötlands runinskrifter 213, is kept in the porch.

A Romanesque church of limestone and granite, with a nave, lower chancel and rounded apse, was built on the site, probably in the later 12th century, with a tower added afterwards. The base of the tower shows a medieval herringbone masonry technique known as opus spicatum, also seen elsewhere in the region, including at the Vreta convent ruin. Cross-arms were added towards the end of the 13th century, and around 1400 the interior received cross vaults.

A visiting 18th-century chronicler described a building extended on both north and south sides with chapels once used for pre-Reformation masses, and noted an old altarpiece with gilded figures, a pulpit dated 1686, and bells cast in 1707 and 1748 hanging in a separate wooden frame beside the stone tower. He also recorded the runestone's discovery in a grave opened in 1729.

By the late 18th century the medieval church could no longer accommodate the growing parish. Plans for an ambitious cross-shaped central church were rejected in favour of a simpler rectangular building in the neoclassical style, retaining the old west tower rather than building the tall spire originally proposed. The new church was built between 1795 and 1796 under county master builder Casper Seurling; sources differ slightly on whether the consecration year was 1796 or 1801.

Inside, notable furnishings include a 14th-century triumphal crucifix hanging in the chancel opening, a mid-17th-century limestone font from Michael Hacke's workshop in Skänninge, and an altarpiece depicting Christ's condemnation by Pilate, painted by Pehr Hörberg in 1798. A painted memorial from 1754 to a former vicar hangs above the sacristy door, and a small medieval stone building, possibly once used for storing tithes, still stands in the churchyard. The church's organ has origins in the early 18th century and was rebuilt several times over the following two centuries.
