[2][3] With its tall spire rising from a flat landscape, it has been called "The Queen of the Marsh".

[2] St Peter's is constructed in a mixture of limestone, greenstone and ironstone, with some red brick.

The tower stands on a plinth and has diagonal buttresses and a single string course.

The top stage contains some patching with brick and a two-light bell opening in each side.

In the north wall of the chancel is a three-light round-headed window and a blocked doorway.

The south wall of the chancel has a small blocked 13th-century doorway into which has been inserted a semicircular window.

It is supported by a pedestal with molded ribs, and stands on a square plinth.
