Mobberley is mentioned in the Doomsday Book but other records make mention of the Parish before the Norman Conquest. The earliest reference to a church dates from 1206 when Patrick de Mobberley founded a small Priory of regular canons of the Order of St. Augustine. As the heart of every Parish is the church, read on. The oldest part of the building, the main body of the nave, date from 1245. In 1450 the Clerestory and Roof were added and the aisles widened and in 1533 the tower was added to replace the original detached one which had fallen into disrepair. The church had major work in the 1880’s when the Chapel and Vestry were rebuilt and the Chancel Arch erected and during these, Saxon remains were found. The church boasts a beautiful Rood screen dating from around 1500 and which bears a number of coats of arms as well as other motifs. The pillars of the screen are richly carved and a
number of faces can be seen. The church also has magnificent 14th century stained glass showing the armorial motifs of a number of local families. The shields were in the original East window but were remade in Victorian times. Another window is in memory of George Leigh Mallory who died on Mount Everest in 1924. The church has a long connection with the Mallory family. The Victorian font is on a pedestal from a medieval water stoop on an inverted Tudor font. On the north wall is a medieval mural of St. George slaying a dragon, above this is a magnificent roof richly decorated on the King posts with late 15th century figures. At the west end there is a Ringers Gallery which has a Jacobean carved rail dedicated to John Baguley and Henry Burges who were Churchwardens in 1693. The organ once stood in the Manchester Free Trade Hall and was once the property of Sir Charles Hallé.
