The cathedral is constructed of three types of stone. The walls and internal piers were originally constructed in a dark purple-brown
Collyhurst sandstone formed in the
Early Permian period. This is now visible only in the tower arch of the nave, in the interior of the Jesus Chapel and in the chancel; as in the early 19th century all the surfaces of the nave and aisles were scored to be encased in
Roman Cement. This damaged the structure so severely that most internal and external stonework had to be replaced in the later 19th century restorations in buff-grey Fletcher Bank Grit from
Ramsbottom. The nave floors have, since the 1960s, been relaid in
limestone from the
Peak District which contains
crinoid fossils.
Restorations By the 1840s the external and internal stonework was in a poor state, partly due to the poor weathering qualities of the Collyhurst sandstone, but also because of an ill-advised attempt to lighten the interior by coating the internal surfaces of the nave with
Roman cement by John Palmer. The external stonework was replaced between 1850 and 1870 in a restoration by
J. S. Crowther, who also replaced the internal stonework of the nave walls and arcades with exact reproductions of the originals. The west tower was heightened in 1868 by J.P. Holden, who also replaced its external stonework.
Basil Champneys added the
vestry, canons' library and western porches in 1898; while
Percy Worthington provided further accommodation to the South-east, originally as a choir school, but subsequently converted to offices. Consequently, the cathedral gives the impression of being a 19th-century structure. To accommodate upgrading work on the cathedral's heating system, in 2013 a temporary wooden cathedral was built on Victoria Street to allow worship to take place.
Furniture Angel minstrels The nave roof brackets are supported by fourteen angel sculptures, each playing a different late medieval instrument, believed to be the gift of James Stanley II. South side (from the east):
Portative organ,
harp,
psaltery (plucked),
dulcimer (played with hammers),
lute,
fithele,
hurdy-gurdy North side (from the east):
clavicymbal,
trumpet,
shawm,
Scots pipes (mouth-blown),
Irish pipes (bellows-blown),
recorder,
tabor It is supposed that, in the 19th century restoration of the nave, the clavicymbal and organ were inadvertently transposed; as otherwise the south side has stringed instruments, and the north side mostly wind instruments. Only the organ presents an instrument that would commonly have been heard in church in the early 16th century; the other instruments would have been more typically used to accompany secular songs and dances. All these instruments, however, might well have been heard accompanying
mystery play performances in the street, and in popular religious processions.
Misericords The cathedral has thirty 16th-century
misericords, considered to be among the finest in Europe. They are similar in style to those at
Ripon Cathedral and
Beverley Minster. Although Manchester's are of a later date, they were probably carved by the same school at Ripon. One of the most notable is N-08, the earliest known depiction of
backgammon in the UK.
Stained glass (1980) window All the Victorian
stained glass was destroyed during the
Manchester Blitz in 1940. Until the late 1960s, only two windows had been replaced, notably the Fire Window by
Margaret Traherne (1966). The dean and chapter commissioned
Tony Hollaway to prepare a scheme for reglazing the cathedral, with priority to the five western windows: St George (1973), St Denys (1976), St Mary (1980), The Creation (1991) and The Apocalypse (1995). To commemorate the restoration of the cathedral following an
IRA bomb in 1996, the Healing Window by Linda Walton was installed in 2004.
Bells The ten bells in the cathedral tower hung for
change ringing were cast by
Gillett & Johnston of Croydon in 1925, and dedicated on 10 November that same year. The tenor (largest) bell weighs 1.3 tonnes and the bells are tuned to the key of D. The bells are rung for church service on Sunday mornings and on special occasions including a visit by
Elizabeth II to distribute the
Royal Maundy. One of the recipients was the tower captain, Roland Eccles, for 35 years of service to ringing and the cathedral community. On 10 November 2025, the centenary of the bells' dedication, a fundraising campaign to re-hang and augment the bells was launched. ==Dean and chapter==
