[4] The tower, with porch below, was added on the south side of the church in the early years of the 15th century.

The replacement chancel was longer and higher and was partly paid for by Salisbury's merchants, among them William Swayne who was three times mayor of the city.

On the north side the Godmanstone and Hungerford families provided the north-east chapel, and Swain built a house for chantry priests (now the vestry) beyond it.

[7] The tower has an east-facing clock, with a pair of quarter-jacks – wooden figures holding halberds which appear to strike the bells.

[8] Above the chancel arch is a large 15th-century doom painting, "one of the best surviving" according to Orbach, which depicts Jesus and the twelve apostles above portrayals of heaven and hell.

[9] In 1850–1860 the tall boxed pews were removed from the chancel, and the high altar and oak screens added.

[3] Work in the chancel by G. E. Street around this time includes the sanctuary walls, the alabaster reredos, the stalls and the stone pulpit.

[11] The Samuel Green organ which had been presented to the cathedral by George III in 1792 was transferred to the church in 1877.

[4] For six years from 1363, the income of the parish was appropriated by the dean and chapter and applied to repairs to the cathedral, and this arrangement was made permanent in 1399.
