Christian churches have existed in Greater Manchester since the Anglo-Saxon era, but no significant Saxon features remain in its listed churches, and the only Norman material is to be found in St Leonard, Middleton. The churches in this list fall into two main groups: those originating mainly from the medieval period, which are in Gothic style, and churches built during the 19th and 20th centuries, mainly in Gothic Revival style, with only a few churches created between these periods. Gothic churches originating from the medieval era include Manchester Cathedral, St Mary, Radcliffe, and St Werburgh Old Church, Warburton. Churches from the 19th century include some of the finest works of the leading architects of the period: George Gilbert Scott (St Mark, Worsley), Alfred Waterhouse (St Elisabeth, Reddish), George Frederick Bodley (St Augustine, Pendlebury), and Charles Barry (All Saints, Whitefield). Built between these periods was the Neoclassical church of St Ann, Manchester. All the above examples are Anglican churches. There are two Roman Catholic churches in the list: Joseph A. Hansom's Holy Name of Jesus, Manchester, and E. W. Pugin's All Saints, Urmston, and one church built for the Christian Scientists, the Edgar Wood Centre.
