The other panel depicts Saint Leonard of Noblac (holding manacles) and Saint Catherine of Alexandria, holding a sword and a book. Located semi-obscured on the south aisle of the church's west wall is The Layer Monument, a marble polychrome mural monument installed circa 1600 to commemorate the merchant, lawyer and mayor Christopher Layer. Its four figurines housed in its pilasters, Pax, Gloria, Vanitas and Labor are sculpted in the art-style of Northern Mannerism. Collectively the Layer Quaternity utilizes esoteric symbolism. The church also has identifiable associations with early British Freemasonry including a 19th-century headstone in its graveyard which depicts Masonic compasses along with the ancient Greek gnostic symbol of the Ouroboros. The church houses one of the largest collections of monumental brasses in England, the oldest dating from the middle of the 15th century. Most of the stained glass dates from the 19th and 20th centuries, although there are fragments of 15th-century glass in the centre window of the north aisle. The east window dates from 1870 and depicts the healing of the Centurion's servant. In the north chapel is a depiction of the Annunciation made by James Powell and Sons, and in the south chapel is a Tree of Jesse from 1916, probably by King of Norwich. The two-manual organ was made in 1888 by Norman and Beard for St Peter's Church, Lowestoft. It was moved to Norwich in 1904 and in 1913 it was rebuilt by Norman and Beard, and moved to the west gallery.
