The chancel, with a now demolished NE sacristy, was rebuilt in the late C13,
the rest of the church, including the nave, clerestory, aisles, chapels, porches and upper part of the tower, was rebuilt c.1330.
The NW vestry was apparently added in the C16.
EXTERIOR A large and handsome church of the C14, very smooth externally as a result of renewal in the C19.
The chancel is late C13
was partially remodelled in the early C14 when it was given an exceptionally fine 5-light E window with intersecting cusped tracery.
The N chancel wall has towards the west two late C13 windows with trefoiled lights and trefoils in the heads.
Further east in this wall is archaeological evidence (roof corbels, piscina and blocked doorway) for a former sacristy or chapel of the C13.
The S chancel wall has three late C13 windows, including two similar to those on the N,
a further C14 low-side window.
The porches are tucked into the western angles between the chapels and aisles, and have lean-to roofs and two-centred openings with hood moulds over restored C14 doorways.
That on the N also has a C14 door into the N chapel.
The lowest part of the W tower is C13
it was completed or rebuilt above this in the C14 at the same time that the rest of the church was rebuilt.
It has a SW stair turret and an embattled parapet with gargoyles.
INTERIOR The interior is lofty, with rich C14 arcades, small clerestory windows, and a high, C19 roof.
The view towards the E is dominated by the enormous early C14 E window with excellent Decorated tracery.
A C13 door in the chancel N wall formerly led to the N sacristy.
The chancel arch is of two moulded orders that die into the walls, and the E wall of the nave may have been rebuilt slightly further E in the C14 as the NE part of the chancel arch partly covers the head stop on the westernmost window in the chancel N wall.
The chancel has a canted, plastered ceiling that was redone in the early C19, but retains C15 ribs and bosses.
The tall, C14 nave arcades are of 5 bays with complex orders of many fine mouldings on equally complex piers with numerous, tiny, attached shafts.
The W responds of both arcades are C13,
that on the S may be slightly earlier as it has a late C12 waterholding base.
The tower arch has three continuously moulded orders to the E and two to the W. The lower part of the tower arch stands on C13 responds similar to the W respond of the N arcade
above this it is entirely C14.
The door to the tower stair is C14 and has wrought iron strapwork hinges.
There are C14 piscinas in the N and S chapels.
The lower part of the C15 rood screen stands in the chancel arch and has panels with flowing, blind tracery.
The panelled, octagonal top part is early C17, and it was re-set on a new base in the late C19.
The E wall of the chancel is lined in alabaster and tiles to a design by Butterfield, with lozenges on the N and S and a more elaborate geometric scheme on the E. The probably mid C19 nave benches, some of which have doors, have simple tracery on the ends.
There is also some good re-set medieval glass, including a C13 heraldic panel, probably for Edmund Crouchback, Earl of Lancaster , a number of C14 panels including figures
heraldry, and a little C15 glass.
There is also some C19 glass, including two windows by Gibbs.
A table tomb, it has a Purbeck marble slab and brass under an elaborate ogee arch.
More recently, however, it has been argued that it was made c.1326 for a later member of the same family, and so is contemporary with the tomb.
There are two C17 benefaction tables, one of 1681 for Thomas Allen, the other of 1679 for William Austin,
the base of the late C15 village cross now stands inside the church.
There is some medieval graffiti in the tower, and an unusual scratched drawing of Ely Cathedral on the tower leads by Dobson Clarke, 1731.
SUBSIDIARY FEATURES (IF APPROPRIATE) Three C14 windows, removed when copies were installed in the C19, survive in the churchyard, but are overgrown.
Separately the C17/C18 churchyard S wall is also listed (LBS 47441) at Grade II.
HISTORY Trumpington is mentioned in the Domesday book of 1086, and while the church itself is not mentioned, a substantial estate in Trumpington then belonged to the Abbey of Ely.
By the C13 Trumpington was a wealthy rectory often held by absentee rectors, including the royal minister Peter des Rivaux, d. 1258, Alan of Rokeland, an official to the bishop of Ely, and also by Nicholas of Hegham, during the period in the 1280s when he was dean of Lincoln.
Their patronage may explain the richness of the late C13 work in the chancel.
The Trumpington family commemorated by the C14 tomb in the N chapel was one of several families who held substantial manors in the parish, and it is likely that they were significant patrons of the contemporary rebuilding of the church.
The chancel glass was apparently destroyed during the reign of Edward IV, and further destruction was ordered by William Dowsing in 1643, although the churchwardens refused to level the chancel steps at that time.
SOURCES John Coales (ed.), The Earliest Monumental Brasses, RCHME: City of Cambridge II Buildings of England: Cambridgeshire REASONS FOR DESIGNATION The church of St Mary and St Michael, Cambridge is designated at Grade I for the following principal reasons: * An architecturally outstanding example of an ambitious and very high quality early C14 church.
Although extensively restored by Butterfield in the C19, the architectural quality of the building has not suffered. * Superb early C14 Trumpington tomb with an outstanding brass, one of the finest in the country. * Excellent medieval fittings including the base of the late medieval rood screen. * Many good wall tablets of the C17, C18 and C19.
