The church at Graimbouville has a single-vessel nave, a transept with the crossing surmounted by a fairly massive quadrangular tower and a chancel comprising a straight bay and an apse. Apart from the transept arms, rebuilt during the 16th c., the building is still entirely Romanesque. Unquestionably the most interesting part is the early 12th c. chancel. Its straight bay is roofed with an intersecting rib vault, doubtless contemporary with the building of the chancel, whose arches rest on gadrooned or two-tiered capitals. The apse, with a semidome vault, is decorated with high open arches with alternate open arches. On the outside, it is propped up by buttresses composed of slender geminated columns; these columns rise from the base up to the roof cornice, passing through the horizontal plain moulding at the base of the windows.
