C14 west tower of 3 stages with recessed spire lit by 2 tiers of double and one of single lucarnes on alternating faces.
Parapet has gargoyles at angles and the buttress tops have foliated gables with projecting grotesque figures.
Stair in south east angle, partly supported on decorated corbels with crouched figures in the angles between the buttresses and the tower walls, and lit by small rectangular barred openings.
In the east wall of the aisle is a probably repositioned C14 geometric window with 3 short trefoil headed lights beneath 2 circles, each containing paired mouchettes, the whole surmounted by a quatrefoil,and contained in a pointed arch with a hood mould.
This window is placed in the blocking of a C13 archway which doubtless lead into a now vanished north chapel, as did the similar blocked archway in the north wall of the chancel and the blocked access to the rood loft in the angle between the chancel and the aisle.
North wall of the chancel has a C12 corbel table reset in the C19, with simple rounded pendent corbels, one of which has a castellated design upon it, and most of which bear masons' marks where not abraded.
Also, built into the later parts of the wall, are 9 fragments of a probably Saxon tympanum.
C12 also are the chamfered plinth and the shallow pilasters near the angles of the chancel.
The south wall of the chancel has a Norman corbel table and plinth as well as a section of string course at the east end which is presumably contemporary.
The impost has a reeded horizontal moulding on it and the stone beneath has the same mason's mark as the 3rd corbel from the west above, thus demonstrating its C12 date.
However, this C12 window itself cuts an earlier blocked opening to the west, fragments of the jambs and sill of which survive.
The blocked window and the evidence of a cruciform plan provided by the coarse walling here and elsewhere together indicate the existence of a Saxon cruciform church, perhaps of minster status.
Otherwise the chancel south wall has a C15 2 light window with ogee heads and quatrefoil beneath a central trefoil and surmounted by a heavy rounded hood mould.
There is also a C14 door with a pointed chamfered head and semicircular hood mould.
South nave wall has elaborate castellated and pinnacled clerestorey of 2 light windows arranged in pairs, and gargoyles.
One C15 triple light window with ogee heads and trefoils beneath a segmental moulded hood mould.
Further west is a C14 2 light window with ogee heads and quatrefoil.
South porch is C13 withes pointed moulded arch, label stops removed.
Inside the porch are side benches and 2 C14 tomb covers bearing effigies of robed priests, one with a chalice, the other with hands clasped in prayer.
Inside, Norman north arcade of 4 bays, first a step, second a step and a roll, third a large roll with billet decoration, and the fourth with deep chevrons in 2 orders.
the 2 piers stand on the circular base of an earlier C12 nave arcade.
C15 figured corbels to nave roof
C14 ones in south aisle
There are 3 similar figures on the principal trusses of the south aisle roof.
Tower arch is very tall, C14, with triple shafts connected by continous hollows with annular capitals and heavily moulded head.
Double chamfered chancel arch is early C13 with collared angle shafts and nailhead decorated octagonal capitals with C19 label stops to hood mould.
C15 square headed aumbries in north and south walls of the chancel.
All glass and fittings C19 apart from the altar rail of circa 1700, very chaste with elegant turned balusters, and the font which is a C12 lead lined tub with continuous tall intersecting pelleted blank arcading on its sides.
Monuments include a wall plaque to Elizabeth Long, d. 1743, in the north aisle with a trumpeting angel and scrolly pediment.
Marble plaque depicting a female mourning figure next to a wreathed urn, John Roe, d. 1765, by T. King of Bath of the north chancel wall.
