The stained glass in Liverpool Cathedral all dates from the 20th century. The designs were planned by a committee working in conjunction with the architect of the cathedral, Giles Gilbert Scott, with the intention of forming an integrated scheme throughout the cathedral. A number of stained glass designers were involved in the scheme, but the major contributors came from James Powell and Sons (Whitefriars Glass), in particular J. W. Brown, James Hogan, and Carl Edwards.
The subjects portrayed in the windows are numerous and diverse. They include scenes and characters from the Old and New Testaments, evangelists, church fathers, saints, and laymen, some famous, others more humble. The windows in the Lady Chapel celebrate the part that women have played in Christianity. The designs in the windows at the ends of the cathedral are based on canticles, the east window on the Te Deum laudamus, and the west window on the Benedicite. The earlier designs are dark, but the later windows are much brighter and more colourful. Much of the glass was damaged by bombing in the Second World War. The windows replacing them were based on the originals, but often using simpler and more colourful designs.
