St. Nicholas' is unusual in that the structure and fabric of the chuch are almost entirely a product of the Decorated period (mid 14th century), with very little later remodelling or additions.
The west tower supports a two tiered spire rising above parapets punctured by quatrefoil openings. The (original) doors are covered with fanciful ornamental tracery. An attractive Perpendicular screen divides the nave to the chancel, where an unusual low passageway links with the vestry.
In the south aisle traces of wall paintings depicting angels surround a wall niche probably meant to receive a statue.
