The church began as a simple grey-stone building around 1200, one of the smallest medieval churches in Södermanland. It was extended westward in the 15th century, and in 1677 the chancel was heightened and given a timber crossvault, along with its distinctive hood roof and spire. The nave's wooden barrel vault followed in the mid-1700s, and a north transept was added in 1755. A timber bell tower dates from the 17th century, rebuilt around 1740.
An unusual feature is the gallery on the north wall, built in 1755 with its own separate entrance. It was funded by Fredrik Bengt Rosenhane of Tista and his wife Eva Sofia Stenbock, reflecting the church's long connection with landed gentry, several of whom are buried in the old churchyard, including members of the Wachtmeister family.
Among the church's furnishings is a font from the first half of the 1200s, one of the oldest items in the building, discovered during well-digging works in the 1950s and now kept in the sacristy. A late-medieval Gothic chandelier and a 13th-century Swedish sculpture of Saint Olof are also notable survivals.
The most celebrated object is the altarpiece, a triptych painted in the 1530s by the German artist Hans Kemmer, donated to the church in 1715. The painting displayed in the church today is a photographic copy; the original is held at Sörmlands museum. The altar decoration surrounding the east window, assembled from fragments of a medieval altar cabinet alongside a modern stained-glass piece by Albert Eldh, was given to the church in 1677.
The pulpit dates from the 1640s, later completed with medieval figures in 1677, and includes an hourglass from 1704. An epitaph to Lorens Stormhatt, created by the Södermanland craftsman Hans Jerling in 1677, hangs on the nave wall. The church's mechanical organ, built in 1878 by Åkerman & Lund of Stockholm and donated by Countess Henriette Wachtmeister of Nääs, survives largely in its original form.
