A cruciform church with an aisleless nave retaining Saxon features, a late-12thc chancel, late-13thc N and S transepts, S porch, 15thc W tower and 19thc N vestry. In the centre of the N nave wall is one small undecorated Early Romanesque window and part of one now blocked (photographed but not described as features). A fine quality 12thc pillar piscina is in the SE corner of the chancel, and a 12thc font is in the W tower. The only other Romanesque sculpture is found on the Transitional chancel arch.

Known in 1086 as Omenie, the main landholders were Turstin fitzRolf and Baldwin from the king. The undertenant was Humphrey the Chamberlain. Domesday Book records a church and mill. Dugdale, in Monasticon Anglicanum. records that a gift of the manor of Ampney Crucis to Tewkesbury monastery was confirmed in 1101 (VCH 62).

A very tall slightly pointed chancel arch; unified in appearance and technique. The shafts evolve smoothly into capitals; each pair close in dimensions and form but varied in decoration in keeping with the date of c.1180 given in the church description.

In the centre of the N nave wall is one small undecorated Early Romanesque window and part of a second, now blocked. The windows are placed very high on the wall, approximately 3.5 m from the floor to the sill. The height of the Romanesque windows perhaps reflects the earlier Saxon elevation.
