[2] The circular shape of the churchyard suggests that a church was on the site before the Norman Conquest, and parts of the existing fabric in the chancel and north vestry date possibly from the 15th century.

The tower has a west entrance with a three-light window above and an inscribed frieze.

The parapet has a balustrade and three finials to each angle, and the spire has three tiers of lucarnes.

There are two fonts, one Norman and simple on a modern base, the other, which was donated in 1755, was previously an Italian marble stoup.

There are a number of monuments, including one on the south side dated 1803 by Sir Richard Westmacott, to the memory of plantation owner William Atherton[6] of Prescot, surmounted with a family crest, with the Latin motto “clarior e tenebris” (brighter after the darkness), and a 1836 brass to George Case, Liverpool mayor and slave trader, which was designed by A. W. N.
