The church houses a wide collection of artworks from different periods. The most recent is a 1997 gift by Lewes artist Michael Cooper of the Crucifixion, an oil on canvas. Other exhibits include a copy of the Cliffe Charter and a water-colour of the church interior from the 19th century; a Spanish rendition of The Ascension dated 1645 (previously thought to be Italian) by a follower of Guido Reni, presented to the church in 1779 by V Vander Guchtius; and a painting of St Wilfred (who brought Christianity to Sussex) by Edward F Skinner who exhibited in London and Lewes 1888-1919. Also possibly by the same artist is the inset oil-on-wood painting of Thomas Becket (pictured).

Among other work on view are two Baptismal rolls, a wooden board listing incumbents since 1320 and circa 1900 painting of Thomas Becket hanging in the Tower.

Of particular interest is a fine royal coat of arms of Queen Elizabeth I (on the west wall of the south aisle). It is modelled in plaster in a lively manner, and painted; it bears the date 1598. Beneath it (pictured left) is an oil painting of the royal arms of England’s first two Hanoverian kings: George I, crowned 1714, and George II who reigned from 1727 to 1760. Records show that a Mr Bugge of Lewes painted the kings’ arms although that hanging in the church today has clearly been altered – but by whom remains a mystery.
