[3] Alterations, including rebuilding of the chancel and the addition of a chantry chapel, were made in 1512 by John Whelpdale, and in 1727 a further stage was added to the tower.

A further restoration was carried out in 1932 by J. F. Martindale, including new windows in the aisles and clerestory and the open timber roof in the nave.

In the aisles are two-light windows with trefoil heads; one of these is original, the others are similar but date from the 1932 restoration.

On the west wall are the royal arms of George IV and a painted text dated 1731.

The stained glass in the east window was made by William Wailes and dates from 1867.

[3] Close to the church is St Mungo's well, a holy well where Christians were baptised in the 6th century.
