[2] The building stands in the heart of the town in a dominating position on Market Hill.

[2][3] A church has been on the site since at least 1180, but the current structure dates from the 15th century, though there have been several restorations in the intervening period.

[4] The church was built in three stages, beginning with the first two bays of the chancel and the base of the tower in about 1330–48.

In 1643, during the Civil War, the iconoclast William Dowsing damaged many of the items in the church.

[4] The church was restored again in 1858–59 by William Butterfield; this included removal of the three galleries and the box pews, re-laying the chancel floor, and replacement of the pulpit.

A further restoration took place in 1968 when the upper part of the tower was replaced, the spire was taken down, and most of Bodley's paintings were removed from the chancel.

The plan consists of a six-bay nave with a clerestory, north and south aisles, a two-bay chancel with the organ chamber and vestry to the north and the Lady Chapel to the south, and an extended sanctuary to the east, and a west tower incorporated in the body of the church.

In the Lady Chapel the font is carved with a depiction of the Nativity, and the reredos is a copy of Leonardo da Vinci's Last Supper.

These were painted by Robert Cardinall, and formerly hung in a position flanking the reredos at the east end of the church.
