In the 14th century the nave, north and south aisles were added. The bell tower (1620) and northeast chapel (1656) were built for the first Earl of Danby and family. By 1763 it was dedicated to St James the Great. There are many historical features in the church, from dates etched into pews by bored youngsters to the medieval doom board, the prime historical feature – one of only five painted wooden tympanums in the country. It is situated above the rood screen with Christ in the centre of the top. The two characters under Jesus are John and Mary the mother of Jesus; these have been painted over in the past by residents of the manor house who had themselves put into the painting. To the right are two figures Adam and Eve being cast out of the Garden of Eden by St Michael wielding his sword. At the bottom left are the dead in their shrouds; some have discarded their shrouds and are on their way to St Peter's gate and the others are headed for the yaws of the Devil, depicted as a firebreathing monster at the bottom right. The painting was designed to put the fear of God into all who looked upon it. This is the third paint scheme of the tympanum. Prior paint schemes did not display the Last Days; rather, they likely reflect the religious attitudes of the local lords.
