Plan: long east end reflects the collegiate status of church from the C12 to the Reformation.
Lady Chapel and south east chapter house C13
church described as "ruinous" in 1413, nave rebuilt early C15.
The porch is stone vaulted with carved foliage bosses and vaulting shafts with shallow-carved capitals.
Moulded inner doorway with a foliage-carved arch.
The west side has two square-headed and one lancet window and a moulded two-centred doorway with a hoodmould and a probably late C17 studded door with Y panelling.
The window in the third bay from the transept is shorter to accommodate a moulded north doorway with steps up, circa late C17 studded door with Y-panelling and an early C19 overthrow with a lamp.
Third bay from the west is blind above a wide crank-arched doorway carved with ballflowers.
Round-headed windows to the second stage indicate C12 origins
Moulded string with fleurons above the arcade, punctuated with carved corbels supporting the shafts to the C19 (Hayward) tie beam roof with arched braces, pierced spandrels and plainer intermediate ties.
Moulded ridge and purlins with moulded diagonal ribs to each bay and carved bosses at the intersections.
Flat C19 (Hayward) aisle roofs with moulded ribs and carved bosses.
The west end has an unusual internal treatment: the projecting, foliage carved sill forms a continuous cornice across the west end with moulded stubwalls flanking the west doorway forming recesses with seats to north and south.
Plain double arch to tower, the piers with engaged shafts, capital carving includes scallops
C14 piscina in the east wall with a cusped head and sexafoil in the gable, the surface dressed back to the wall plane.
The south wall contains an early C15 triple sedilia, very damaged, with lierne vaulting.
The rear, to the aisle, includes a tomb chest with a vaulted recess and remains of high quality figure carving and original colour.
Fine C13 Lady Chapel with north and south doorways from the aisles with triple chamfered arches on big half shafts with bell capitals.
Late C13 double-gabled piscina with trefoil-headed arches, re-sited, on the south wall.
C19 Perpendicular drum pulpit on a wine glass stem, carved with figures of saints.
The figure of Sir William, leans on one elbow with his family in relief, kneeling on the chest below.
Spectacular monument of 1911 by Caröe, executed Dart and Francis of Crediton, to Sir Redvers Buller, covers the tower arch, facing the nave.
Terra cotta sculpted figures, decorated with mosaic
iconography of the memorial thoroughly military with warrior saints and a frieze of Victoria crosses.
Stained Glass: Several good windows by Lavers, Barraud and Westlake
