Great Haseley is a small village, 9 miles SE of Oxford. The large church of St Peter's comprises a tall chancel, a nave with S and N aisles and a W tower. It dates from around 1200. The nave and its aisles are late 12thc and include high-quality features. The N and S aisles have sculpted capitals on the piers of the three bay arcades. The nave W doorway is Early English and of three orders, reset in the 14thc tower. There is also a Romanesque plain font.

In 1086 Domesday records that Miles Crispin of Wallingford held the manor at Great Haseley. By the 13thc it was held by Roger Bigod, 2nd Earl of Norfolk.

The church is part of the benefice of Great Haseley, Great Milton and Little Milton.

St Peter's, Great Haseley, is one of several churches in this area (Elsfield nearby, and Caversfield near Bicester) that display similar late 12thc capitals on responds and piers. The capitals are notably shallow, often with trefoil, quatrefoil or cinquefoil leaves that join to form volutes. These capitals are similar to many of those of 1180-90 from the former St Frideswide's Priory (Oxford Cathedral).
