Exterior The church is constructed in
sandstone ashlar with
slate roofs. Its plan consists of a 5½-
bay nave with a
clerestory, north and south
aisles, a three-bay
chancel with a two-bay organ-house to the north, a three-bay chapel on the south with an attached
vestry, and a west
steeple with a north porch. Its architectural style is
Decorated. The
buttressed tower is tall and in three stages. On its west face is a small two-light window in the bottom stage, and a
lancet window in the middle stage. On the north and south sides are diamond-shaped clock faces. In the top stage are two
louvred bell openings on each side, each with a
crocketed
gablet. Above them is a
cornice with
gargoyles, and a
parapet with corner
pinnacles. The pinnacles are linked by
flying buttresses to smaller pinnacles clasping the spire. The spire is tall and octagonal. At the base of the spire are two-light
lucarnes with gablets, and above these are two tiers of small lucarnes. To the north of the tower is a two-storey gabled porch. In its lower storey is a doorway flanked by crocketed
niches, and in the upper storey is a two-light window flanked by blind windows. Along the sides of the clerestory are buttresses rising to pinnacles, each bay containing a pair of two-light windows, with a single-light window in the half bay. At the east end is a pair of octagonal pinnacles. Along the sides of the aisles are buttresses rising to gablets, and each bay contains a large three-light window. At the east end of the chancel are diagonal buttresses rising to pinnacles. The east window is large with five lights. On the north side of the chancel is a three-light window, and a parapet with open zig-zag work. The organ house has three-light windows on its north side, a large four-light window on the east side, and corner pinnacles. The features of the south chapel are similar. The vestry has a west door, a three-light east window and coupled lancets on its side. incorporating photographic passages including a street scene from the 1972 Preston Guild processions. The church is also appointed with windows by
William Wailes, dating from the 1850s and, under the tower, a window by Lancastrian firm
Shrigley and Hunt dated 1907. The earliest memorial is a
brass dated 1623. Elsewhere there are memorials to members of the
Hoghton family, and in the tower is the tomb-recess of Thomas Starkie Shuttleworth who died in 1819. In 1889 it was rebuilt by William Hill and Son and moved from its position in the west gallery to the north of the chancel. The organ was rebuilt in 1965 by Hill, Norman & Beard, and repairs were carried out by
Harrison & Harrison in 1972. In 1989 David Wells carried out a comprehensive rebuilding. The tower contains twelve bells cast by the
Whitechapel Bell Foundry. The heaviest eight were cast in 1920 for
Holy Trinity, Bolton. These were transferred to Preston in 1997 with the addition of two trebles. Two further trebles were added in 2003. The original ring of six bells, cast by Thomas Mears II in 1814 and Mears & Stainbank in 1934, were removed from the tower and later installed at Southminster Presbyterian Church,
Pittsburgh, Pennsylvania, in the
United States, where they now form a ring of eight. ==External features==
