The church is dedicated to St Nicholas, Bishop of Myra (now Demre in modern Turkey) in the 4th century; a signatory of the Nicene Creed; patron saint of Russia and Greece, and of children, merchants, pawnbrokers, sailors, scholars and travellers.

The 12th-century north doorway was moved out and reset in its present position in the 15th century, surrounded by a 19th-century porch.

The Norman doorway has three orders and the middle columns have spiral fluting and shaft ring enrichments.

The capitals are carved with volutes and foliage; the arches are also decorated lavishly with chevrons and billets.

There is a fine Elizabethan monument to Sir Richard erected by his wife Susannah, located on the north wall of the chapel.
