File:Baumber, St Swithin's church, interior looking west (30802490288).jpg

The church dates from the eleventh century onwards, although the majority of the church is of redbrick from the 18th century when the stone church was clad in brick, and refenestrated in 1758. The brickwork has decorative features. The roof is of lead and slate.

There is a two stage western tower of redbrick, but at the base there are possible remains of Saxon work inside. The top of the tower has battlemented parapets. The inside of the tower has massive wooden trusses.

The nave has north and south aisles, with three bay arcades dating from the thirteenth century. Much of the interior is in the 18th century Gothick style. The chancel arch has been replaced by an 18th century three bay screen with ogee arches and gilt decoration and finials. There is a Royal Coat of Arms above the screen.

The north aisle contains three old bells which are quite large for a small church. They were taken down around 1950 when considered unsafe.

The nave has several hatchments to the Clinton and Lievesey families. There is a vault and memorial slabs to the Clintons in the chancel. At the south west end of the nave is a large ledger slab to John Eland d.1473, and his two wives.

The chancel is entered by three steps up from the nave, and is typically Georgian. The altar is another three steps higher and there is no east window.

The church was restored in 1891-2 by W. Scorer.
