Plan: West tower, nave on medieval foundations, three-bay north aisle, chancel and vestries.
Exterior: Somerset Perpendicular style tower, nave and aisle, Early English style chancel, the latter chosen because of the13th century foundation date, although there was no evidence of a medieval chancel.
In the tower west window, fragments survived of early 14th century Dec tracery.
Interior: Tower arch with C14 wave mouldings.
The open timber roofs have small hammerbeams and angel terminals.
South of the chancel arch, a small C15 trefoil-headed niche or piscina from the old church.
Ribbed wagon roof painted with angels etc. Principal Fixtures: Timber reredos, c.1870, painted and gilded, with many-gabled top and figures of the Evangelists.
On the east wall are painted big worshipping angels, by the Rev. R. Hautenville, the Rector in 1870.
Angular pulpit, corbelled off the wall north of the chancel arch.
Purbeck marble font, 1879, with trefoil panelled sides.
Good colourful Victorian stained glass.
In the south nave wall, first from east, Heaton & Butler, c.1873, with medieval fragments in the top lights
There are other fragments of medieval glass, some of it French or Flemish, in the top lights of various windows and in the vestries.
The stained glass in St Mary's church provides some spectacular colours.
He often favoured a 13th century Gothic style, although he could equally well turn his hand to Somerset Perp, as here.
The rebuilding reflects the mid-Victorian spread of Clevedon as a fashionable seaside resort. * The medieval origins of the church are of historic interest, although the survival of fabric is fairly small: the tower base, which before Norton exhibited slight remains of 14th century Dec tracery etc., was reworked in Perp style to accord with the rest, and only the walls of the tower base can be safely regarded as genuinely medieval.
