There are broad transoms to the bottom of each window which are carved with shields.
This sits above a small three-light mullioned window with stained glass.
The majority of the windows have clear glass providing an abundance of natural daylight, and the walls are whitewashed, with the stone nave arcade, chancel arch and apsidal arch left exposed.
There is a mid-C19 stone font of marble columns and carved cherubs and fleur-de-lis surmounted with a wooden font cover.

The apse windows contain figures of Christ, a Madonna and the saints from C19 stained glass reset in clear glass.
HISTORY: There was a medieval church on this site until 1826 when a faculty was granted for the building of a new church.
The clear glass windows, some peppered with reset stained glass, enhance the airiness of the interior.
There are also some fixtures of note, including font, pulpit and the pews and monuments in the galleries.
