St Helenís was completely rebuilt externally in 1853 by Stephen Lewin. The style is Early English, with plate tracery in the windows and an imposing tower.
The nave interior retains its 13th century Early English arcades.
Both nave and chancel with their plate tracery date from 1853-54.
The tall ashlar tower dates from 1853. The design is unusual, with arcades of five lancets in the belfry stage.
Pevsner makes particular comment on the crocketed gable on the short buttress at the south-west corner - "naughty", he says.
The Early English style west doorway of 1853 has four orders, and dog tooth decoration round the arches.
