First built in Saxon times, there is only a small piece of carved stone left, acting as a sill for the Aumbrey on the left of the Altar. Of the Norman replacement only the south wall remains, with a small window cut into it and a late perpendicular doorway containing the original oak studded door, once covered with leather. Over the door lintel is the Norman Tympanum, depicting the Tree of Life, to the right of the door pillar is the Mass Dial and by the door lock is the Consecration Cross, cut into the stonework. Remains of Early English plate tracery can be seen in the heads of some of the windows.

In the Chancel, on the right hand side is a black marble slab commemorating a former Lord of the Manor, Thomas Nicholas, whose tomb is in the sealed rectorial vault. The rest of the church was extensively renovated in 1849/50. The Harrison organ was given to St. Peter's in 1948 by Major G.Lethbridge-Galton in memory of his wife and paid for by the sale of a herd of cows. The present pulpit came from a redundant church in Norfolk in 1968. There are two bells in the bellcote, one dated 1671.

As you walk round the outside of the church, you can see the small Norman window with the stone at the top, marked to make it look as if it is many stones.
