Stone (part rendered), tile and slate roof
PLAN: Chancel, nave, south porch, north aisle and Lady Chapel (formerly vestry). EXTERIOR: The church comprises a late C12 nave with north (reset: slightly chamfered arch) and south (also reset: one order of columns with scallop capitals and with a roll-moulding) and chancel arch (with possibly C13 painted lozenge and spiral decoration) of this date
The chancel with three stepped lancet lights is C13, as are the two south and one north square-headed lights to the chancel and the three dwarf buttresses supporting the east wall
In 1864-5 G.E. Street added an arcaded north aisle in the Early English style with dogtooth in the abici of the arcade piers (the arcade extending alongside the chancel as a two-storey vestry, later refurbished as the Lady Chapel) in which the C12 door was reset
C13 piscina with shouldered lintel
stalls and pulpit by Street
The Norman columns at the chancel arch retain their original paint, with spirals on one and lozenges on the other
James, parish church of Cowley village, came to Osney Abbey in 1149, and the remaining Norman elements may date from soon after that
