St Michael's Church, is the only church in Chirbury, and is dedicated to Saint Michael the Archangel. It is Church of England (Diocese of Hereford) and the Chirbury ecclesiastical parish covers a smaller area than the civil parish, including Wotherton, but not Brompton, Marton or Middleton.
Originally an Anglo-Saxon church, founded in 915 (with the building of the fort) or possibly earlier, the current building largely dates to the late 12th century with the tower constructed around 1300, and a short chancel added in 1733. The church was restored in 1871–72 by Edward Haycock junior. The tower and body of the church are constructed in limestone rubble with pink sandstone ashlar dressings and slate roofs; the chancel is in red brick with a tiled roof. The church was reformed into the priory church of the Augustinian Chirbury Priory upon the moving of the order from nearby Snead by 1227. With the dissolution of the priory in 1535 St Michael's became a parish church once again. The church building is a Grade I Listed building. Remnants of the former priory can be seen in the churchyard and some stonework was also incorporated into the adjacent Chirbury Hall.
