The crypt served as an air-raid shelter during World War II. During the Blitz on 19 March 1941, incendiary bombs landed on the roof causing it to collapse, burning into the nave. The walls and the tower remained standing but much of the interior was gutted. The church was restored by Sir Albert Richardson in 1953. As part of the post-war restorations, stencils of Mary the Mother of Jesus and St John the Evangelist were installed either side of the Cross (forming a traditional rood) in the side chapel of St Alfege with St Peter by the tempera artist Augustus Lunn.
