<P> Mosaics installed during the period 1912--1916 were mostly done by devotees of the Arts and Crafts Movement . Those in the Lady Chapel were installed by the experienced mosaicist Gertrude Martin (who had worked with George Bridge), in 1912--1913 . The worked was supervised by Anning Bell and Marshall, who later designed the mosaic of Christ Enthroned which is above the entrance to the cathedral . The mosaics (paid for by the 4th Marquis of Bute in the chapel dedicated to Saint Andrew also belong to work of the Arts and Craft Movement . </P> <P> The 5 - year period (1930--1935) saw a tremendous amount of work done and saw mosaics placed in the Lady Chapel, in the alcoves above the confessionals, in the crypt dedicated to Saint Peter as well as on the sanctuary arch . </P> <P> No new mosaics were installed until 1950 when one depicting St Thérèse of Lisieux (later replaced by a bronze) was placed in the south transept and another (in memory of those in the Royal Army Medical Corps who died in World War II) in the chapel of Saint George in 1952 . From 1960--1962 the Blessed Sacrament Chapel was decorated in a traditional, early Christian, style with the mosaics being predominantly pale pink in order to afford a sense of light and space . The designer, Boris Anrep, chose various Eucharistic themes such as the sacrifice of Abel, the hospitality of Abraham and the gathering of the manna in the wilderness as well as the Feeding the Multitude and the Wedding Feast at Cana . In his old age, Anrep also acted as adviser and principal sketch artist for the mosaics installed in the chapel of Saint Paul (1964--1965) These mosaics depict various moments in the life of Paul; his occupation as a tent - maker, his conversion to Christ, the shipwreck on Malta and his eventual execution in Rome . </P> <P> It was not until the visit of Pope John Paul II in 1982 that the next mosaic was installed above the northwest entrance . Rather than a scene, this mosaic is an inscription: Porta sis ostium pacificum par eum qui se ostium appellavit, Jesus Christum (May this door be the gate of peace through Him who called Himself the gate, Jesus Christ). In 1999 the mosaic of Saint Patrick, holding a shamrock and a pastoral staff as well as trampling on a snake, was installed the entrance to the chapel in his honour . In 2001 a striking mosaic of Saint Alban, strongly influenced by the style of early Byzantine iconography, was installed by the designer, Christopher Hobbs . Due to the very favourable reception of this work, Hobbs was commissioned for further mosaics: the chapel to Saint Joseph which contains mosaics of the Holy Family (2003) and men working on Westminster Cathedral (2006). Hobbs also did the chapel in honour of Saint Thomas Becket illustrating the saint standing in front of the old Canterbury Cathedral on the chapel's east wall and the murder of Thomas on the west wall . The vault is decorated with a design of flowers, tendrils and roundels. (2006). As of 2011, there were plans for further mosaics, for example Saint Francis of Assisi and Saint Anthony in the narthex </P>
