The panelled timber ceiling dates from the 16th century, and has been much restored since.

The roof bosses feature decorative carvings of flowers, fruit, foliage and stars.   There are also five human heads.  A bearded face above the site of the medieval high altar is said to be the likeness of Ralph Langley, Rector of Prestwich from 1493-95.

This part of the church is known as the nave (from the Latin word meaning ship).  The ship was an early symbol for the Christian church.
