The first church on the site is thought to be a small wooden chapel built 1219 by
Bishop Poore as a place of worship for those working on the site of the new cathedral. This was soon replaced by a stone building, The church had its own parish by 1246. In 1447 the
chancel collapsed, leading to extensive rebuilding and enlargement; a fragment of 13th-century masonry remains at the west end of the south arcade of the chancel. 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. The chancel aisles were also rebuilt, and Swayne provided a
chantry chapel in the south aisle (now the Lady Chapel). 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. The 15th-century roofs are embellished with carving and many figures of angels; Orbach calls the nave roof "ornate and dainty". The great west window is from the same period. The tower has an east-facing clock, with a pair of
quarter-jacks – wooden figures holding
halberds which appear to strike the bells. They were installed in 1581, at the same time as the quarter bells, although the present figures date from the late 17th to late 18th century. == Interior ==
