The foundations of the Norman chancel were found under the nave in 1956-1957.
C14 north wall
The C14 north chapel (now the vestry) has a two-light window (tracery much renewed), Woodyer's eastward extension is largely Decorated style but has a three-light Perpendicular east window.
The south aisle is buttressed, one buttress partly rebuilt in red brick with three-light Perpendicular windows (much stonework renewal) with cinquefoil-headed lights and Tudor arched heads.
The spandrels are carved with blind tracery.
INTERIOR: The nave has a medieval four bay Perpendicular crownpost roof, the crownposts with moulded capitals and bases and four-way bracing.
Probably late medieval tie beam and common rafter roof to the south aisle.
C19 reredos of stone panels with painted figures under ogee arches, the stone panelling extending across the width of the sanctuary.
Impressive late medieval (restored) timber screen with rood loft with lierne vaulting extends across the width of the nave and south aisle, the main doorway to the nave off-centre and the south end projecting across one of the aisle windows.
1827 timber drum pulpit designed by Blore, originating from Westminster Abbey: a timber drum with well-proportioned blind Gothic tracery below crocketted gables.
Stained glass includes a 1903 Morris and Co window to Burne-Jones's design.
C14 tomb canopy on north wall.
Wall monuments include four of early C18 date by Henry Cheere (Pevsner) to members of the Borrett family.
