south doorway of circa 1130 (Sedding).
2 Norman windows on north side of church and 2 on south.
The Norman church appears to have been of cruciform plan.
The north doorway, which was not accessible at time of survey , was dated by Sedding to 1080 and the south doorway some 50 years later.
The south transept, Sedding suggests was lengthened in the circa late C12, the transepts originally being of equal length.
In circa C14 the north porch was added and the south porch, possibly of the C14 was rebuilt in circa C18.
Sometime possibly in the C14 a small chapel was added on the north side of the chancel
in circa 1500 the rood screen was erected.
North porch: circa C14 the outer door with a very hollow chamfer to the almost round headed arch which has a double roll mould with cavello in between and large pyramid stops.
The inner north door arch (not accessible) has Norman label and impost mouldings with a plain tympanum (Sedding).
North wall of nave has a Norman window
There is evidence of part rebuilding below the eaves in the south transept which has a circa C14 decorated 2-light window with a cusped head and two 2-light windows with cusped heads in the east wall.
South door with circa early C12 arch, 1 shaft circular and the other octagonal with differing capitals.
Rood Screed circa 1500 with Perpendicular tracery.
Canopied recess of circa C14 on south side of chancel.
Roman stone at west end of south transept inscribed IMP C G VAL LIC LICIN, previously used as coffin rest at lower church stile (qv. lychgate to south of Church of St Materiana) until 1888.
