The church of St. James, Southbroom, stands on the edge of the green, next to the pond known as the Crammer. It was a chapelry of St Mary's, Bishops Cannings until 1832. The civil parish of Bishops Cannings extended as far as the church until 1835, when the boundaries of Devizes borough were expanded. St. James's is first recorded in 1461. The tower is 15th-century while the body of the church was rebuilt in 1831–2; the east window is by Wailes. After completion of the Le Marchant Barracks in 1878, St. James's became the garrison church of the Wiltshire Regiment. The building is Grade II* listed and underwent an internal re-ordering in 2008. Today the church is evangelical in style.
