Gable ended slate roofs with decorative C19 ridge-tiles.
The nave, aisles, chapels and porch date from a rebuilding in the circa late C15.
with its mullion windows and crenellated walls it appears to be C17 but might have been built later, re-using old materials.
Interior: porch has very good granite rib-vaulted ceiling with 6 shafts supporting the moulded ribs and large carved bosses at their intersections.
Holy water stoup with carved granite bowl.
C15 granite south doorway with 4-centred arch and double roll-moulding.
The 8-bay Beer stone arcades have clustered columns with individual carved capital to each shaft, moulded 4-centred arches between.
C13 trefoil-headed piscina in south wall of sanctuary and adjoining it is the springing of an arch apparently for a sedilia but cut off by the later arcade.
Filling the eastern end bay of each arcade is a section of the C15 rood screen, considerably restored.
The parclose screens in the adjoining bay are also medieval but somewhat restored.
The wagon roofs have been completely renewed during the restoration as has the seating throughout and the pulpit.
Just inside the north doorway is another stoup with arch above and the front of the bowl carved with vine and grape device.
