The N aisle and all or part of the S aisle were added in the later C12
There was further remodelling in the C15, when the tower and clerestory were added and the E window replaced
EXTERIOR: Three stage, C15 embattled W tower with very high, moulded plinth, the stages separated by strings
Blocked 4-centred W door with continuous moulded arch, square hood mould and carved spandrels
There is a blocked late C12 doorway in the N (the VCH suggests this led to a former chapel or sacristy, though this need not have been the case and it may have been simply a priest's door) and to the right of it a round-headed recess, probably for a tomb, and perhaps also dating to the late C12
The chancel S windows are both heavily renewed, but are C14 Decorated in style
There is a single C19 lancet with a trefoiled head in each arch, but these are set within blocked openings, the westernmost rounded headed and probably a former Georgian or churchwarden¿s gothic style window of 1808, the other two four-centred and probably reused C15 windows removed in the C19
Tall, pointed tower arch the full width of the tower, with three chamfered dying orders of C15 form
The nave has a very shallow, plain roof probably of the C15, much restored in the C20
The E respond and 1st pier of each arcade has a square, C12 capital, while the other capitals on each side are moulded
Tall, C15, pointed chancel arch of two hollow chamfered orders, with a hood mould to the nave side
The blocked C12 door or opening to a former chapel is visible in the S wall of the chancel, and in the S chancel wall there is a blocked rectangular opening, apparently a former squint
C19 doorway to the vestry and arch to the organ chamber on the N. The chancel has a 3-seat, C14 sedilia and an aumbry, but no piscina
The rounded bowl has a king's head in the style of Edward I, a winged figure, a monster and one unrecognisable motif on its lower corners
Three seat early C14 sedilia in the chancel, each niche with a trefoiled ogee head and the seats level
There is a hood mould with head stops and finials over each arch, and the niches are divided by moulded shafts very similar to the outer shafts on the font, suggesting a similar date for the font and sedilia
C19 encaustic tiles in chancel
Polygonal C19 timber pulpit with traceried sides
A brass to Horatio Woodhouse (d.1679), rector for almost 37 years, in the chancel and some C19 wall slabs
This arrangement was altered, and advowson of Collingtree fully separated from that of Milton Malzors, in the mid C15
The late C12 aisles at Collingtree are the earliest evidence for a church there, but Collingtree itself existed at the time of Domesday and the aisles were probably added to an early C12 church comprising an aisleless nave and square chancel
The tower dates to the C15
