Österhaninge kyrka

The church began as a single-naved building with a narrower chancel, completed by the early 1300s, with roof timbers in the nave dated to around 1320. During the later 15th century the chancel was widened to match the nave, the present sacristy and porch were added, and the nave received its star vaulting. The tower was built in stages up to the later 16th century, and its slightly twisted form is said locally to have driven the master builder responsible to despair, with legend claiming he hanged himself inside it.

In 1663 a burial chancel was added at the east end for Admiral Claes Bielkenstierna, replacing the chancel's original gable with a hipped roof. Its most striking feature is a large marble memorial by the Flemish sculptor Nicolaes Millich, commissioned by the admiral's widow after their son died in the naval battle of Öland in 1676; the monument was finally installed in 1683, an allegorical tribute to the dying Bielkenstierna line. A gravestone for Hans Claesson Bielkenstierna and Elisabeth Gyllenstierna, once set over a tomb in the chancel, was later moved into this burial chapel.

The church's furnishings span several centuries: a limestone font from Gotland dates from the 1200s, and a carved pulpit with small columns is from 1623. A medieval wooden figure of the Virgin from around 1300 and a fragment of an apostle figure from the 15th century also survive, alongside a 13th-century triumphal crucifix, though that crucifix is now held in the Swedish History Museum rather than in the church itself.//

A notable 20th-century addition is the altarpiece, created in 1973 following renovation work led by architect Jörgen Fåk. Worked in linen with gold and silver embroidery by textile artist Anna Lisa Odelqvist-Kruse and embroiderers Inga-Lisa Nordsten and Barbro Hillerstig, it depicts Christ's resurrection surrounded by scenes drawn from the Old and New Testaments, including the story of Jonah, understood as a foreshadowing of the resurrection theme.

In the churchyard lies the grave of Fredrika Bremer (1801–1865), the novelist and campaigner for women's rights, whose writing argued for women's access to higher education and professional life and who became internationally known through translations of her novels.
