chapel of 1517, porch rebuilt 1825, south chapel restored 1829 under the supervision of GA Boyce, with Watkins as mason
MATERIALS: snecked and coursed rubble local purple and volcanic masonry with Beerstone and (rare in Devon churches) Ham Hill stone dressings to the medieval masonry and Bathstone dressings to the C19 rebuilding.
The exterior has a plinth with moulded string and tall parapets and is mostly embattled with lavish carving, not only on the Perpendicular tower but particularly to the Greenway chapel and porch and also to Ashworth's work which is characterised by richly-carved corbel tables below the parapet including outsize gargoyles.
5-light 1850s traceried east window with intersecting tracery, hoodmould and carved label stops. north and south chancel windows are also Victorian, 2-light and traceried with transoms.
The south side is buttressed with elaborate buttresses with set offs, carvings and pinnacles, some heavily restored and an a frieze of carved ships etc on to the embattled parapet.
Buttresses with set offs, 3 dimensional carvings and niches
friezes below the stepped pierced parapet are carved with motifs appropriate to Greenway's mercantile interests:-ships, emblems of the wool trade etc
arms of the merchant venturers' and drapers' companies and a string course carved with scenes from the life of Christ.
Black letter carved inscriptions record Greenway's foundation of the chapel and date of death.
Above the springing of the arch of the moulded doorway the facade is carved with blank tracery, heraldic shields, texts and niches.
The west return is local rubble rather than Beerstone ashlar and the poor condition of the parapet carving and the carvings on the buttresses indicate just how heavily restored the carved work is on the show fronts of the porch and chapel.
The north side of the church is wholly Ashworth and has a plaque "restored and enlarged 1853-1856", except for the presumably re-sited round-headed C12 doorway with dogtooth decoration.
INTERIOR: the interior of the porch is very fine with a stone vault panelled with ogee reticulation and carved motifs.
Above the inner doorway a tympanum shows a carved relief of John and Joan Greenway kneeling on either side of a carving showing the Assumption of the Virgin.
The interior of the church has C19 timber tie beam roof trusses with brackets on stone carved corbels
Chancel arch has blind panelling to the responds and capitals carved with boars' heads and a phoenix.
2-bay Beerstone arcades into the chancel chapels are probably medieval
Tudor arched clerestory windows appear to be wholly Victorian.
