Bäcks kyrka

The present stone church was built in 1749, with its tower completed the following year. It replaced an earlier wooden church on the site, said locally to have stood on a rise opposite the Ymsjöholm avenue; that older building, possibly originally of stave construction and later of log form, was demolished to make way for the new church, as parish records from 1748 note the builder's first task was clearing the old structure.

The new church was raised by local farmers with support from Major Carl Hierta of Borrud, and much of its stone reportedly came from the ruined medieval stronghold of Ymseborg, west of the lake. Work is said to have begun early and continued long into the evening during the building season. The walls were rendered and painted pink, a colour scheme recently rediscovered and preserved on a small section inside the tower's north window opening. The building is a simple hall-church (salkyrka), with a later sacristy added to the north side of the chancel, built sometime before 1829.

Much of the interior visitors see today dates from a refurbishment around 1925, when a new organ, bells and stained glass in the chancel windows were installed; further work took place for the church's 200th anniversary in 1949, and later maintenance has continued. The nine-stop organ from this period, built by Nordfors & Co, sits on the west gallery.

Among the church's older furnishings is a soapstone font from the 13th century, and a wooden Madonna figure that is thought to be strikingly old, though sources differ on its precise date: one account places it in the same century as the font, while a more detailed architectural record dates it to the late 12th century, describing it as one of the oldest and most unusual of its kind in Sweden, possibly of North German origin, though now damaged and missing the Christ child figure it would have held.

The altarpiece was donated in 1751 by Carl Hierta and his wife, initially unpainted; it was decorated in 1765 at the parish's expense, with the painting attributed to Gabriel Lindman. The church also holds two medieval bells, one of late medieval type without inscription and a smaller Romanesque bell from the 13th century, along with textiles surviving from the 17th and 18th centuries.
