A stone church was likely built at Ringarum during the 13th century. This medieval building was demolished when the present church was constructed between 1777 and 1779 in the restrained Gustavian style typical of the period. Interestingly, parts of the old church's south and west walls were retained and incorporated into the new structure, giving a physical link between the two buildings across five centuries.
The church has a stone structure with a rectangular nave and a three-sided chancel to the east, with a tower at the west end. A semicircular sacristy is attached to the east of the chancel, and a further sacristy lies to the north.
Among the furnishings, visitors can see a brass font made in 1663 at the Gusum ironworks, a notable example of local craftsmanship from the era, and a pulpit dating from 1642, which predates the current church building itself.
The church has had several organs over its history. An early instrument with six stops was built in 1648 by Simon Valentinson of Söderköping, later repaired in 1682. A larger organ with eighteen stops across two manuals and pedal was built in 1808 by Pehr Schiörlin of Linköping. The present main organ, a mechanical instrument, was installed in 1918 by E. A. Setterquist & Son. A smaller mechanical chancel organ with five stops was added in 1981 by Anders Perssons Orgelbyggeri.
