The stained glass throughout the Church is the work of Burlison and Grylls. In the North aisle the windows portray the Prophets, Priests, Kings and Martyrs of the faith; whilst in the South aisle they depict the Saints and symbols of the four nations of the United Kingdom. In the clerestory a ‘Chorus Angolorum’ holds a continuous scroll inscribed with the Magnificat beneath them. The coats of arms remember families connected with the Grosvenors.
