Bjälbo Church, Medieval church in Mjölby Municipality, Sweden

Bjälbo Church is a whitewashed stone church with a west tower 37.5 metres high, among the tallest in Östergötland. The nave and sacristy have gabled roofs, the chancel a hipped gable roof, all covered in brown wood shingles. Inside, the nave has a barrel vault and the chancel a helm vault; the chancel was built in 1786–88 under builder C. Seurling. The church door carries 13th-century wrought-iron decoration.

A stave church stood just north of the present site before the stone church was built in the 12th century. The west tower was finished shortly after 1220; dendrochronological samples show its timbers were felled after 1210, around 1215 and around 1220, which points to Ingrid Ylva, widow of Magnus Minnesköld, as its builder. In 1786–88 the choir was rebuilt under the master builder C. Seurling.

The parish church still belongs to the Skänninge pastorate. Inside, the altarpiece was painted by Pehr Hörberg in 1810, the font dates from 1658 and the organ gallery carries apostle paintings made in 1760 by Vadstena church painter Sven Gustafsson Stoltz. The tower room on the second floor is called "drottning Ylvas kammare" after Ingrid Ylva.

The church stands on the plain about 5 km west of Skänninge in Östergötland, with two runestones, Ög 64 and Ög 66, beside it. The 37.5 m tower is among the tallest in the province, so it works as a landmark when approaching across the fields. The interior is Gustavian in style, with a barrel vault and a helm vault over the choir.

Dendrochronological samples from the tower's timbers show the trees were felled after 1210, around 1215 and about 1220, which rules out Birger Brosa (died 1202) and Ingrid Ylva's husband Magnus Minnesköld (died c. 1210) as builders; their son Birger was still a minor. A room on the tower's second floor is called "drottning Ylvas kammare", Queen Ylva's chamber.
