St Augustine's is a Grade 2 listed building that dates back to the 12th century

It consisted then of the present nave and probably a small chancel. In the 13th century the chancel was rebuilt and widened towards the north, and the small tower, which projects some 4 ft. into the west end of the nave, was added. The south aisle was built at the end of the 13th century and the north aisle some twenty-five years later, though the latter was considerably repaired at a subsequent period. The fabric was restored in 1863, and the vestry and porch are modern.

The chancel is lighted by a modern traceried window in the east wall, an original lancet at the east end of each side wall and a 14th-century low-side window at the north-west, the last being of one trefoiled light with a transom, below which the light is blocked. All these windows have modern rear arches. At the west end of the south wall are a modern arch and doorway to the vestry and organchamber, and at the east end is a piscina with a cinquefoiled ogee head and modern bowl. The wide chancel arch, dating from the 13th century, is of two chamfered orders, the outer continuous down the jambs and the inner supported by semi-octagonal responds with moulded capitals. Above the capitals the arch has been rebuilt.

The nave is of three bays, and has a modern clearstory with circular cusped windows. Both arcades are of three pointed arches supported by octagonal pillars and responds with moulded capitals and bases. The south arcade dates from the end of the 13th century, and the capitals of its responds are embellished with nail-head ornament. The north arcade is of about 1320, though the mouldings of its capitals and bases seem to have been somewhat altered at a subsequent period. The pointed tower arch in the west wall of the nave is of a single order with an indented label, and dates from the early 13th century; the responds, which are formed of octagonal shafts with moulded capitals and bases, do not appear to be in their original position. There is a square-headed recess to the south of the chancel arch which probably formed the reredos of a nave altar, but its lower part is now built up. At the north-east of the nave is a small ogee-headed piscina of about 1400, without bowl. Both aisles have been extensively restored, and, with the exception of some old jamb stones re-used in the north aisle, the windows and doorways are modern. Several fragments of mediaeval wrought stones have been incorporated in the walling of the south aisle, among them a 15th-century carved head.

The tower, which has been considerably restored, is of three stages, and has a modern saddle-back roof. The windows of the ground stage and bell-chamber are modern, and the ringing chamber is lighted by small loops on the north and south.

The font and pulpit are modern. There are some fragments of old painted glass reset in the south window of the vestry, and on the floor of the chancel are several mediaeval encaustic tiles.
