Roger de Poicteau also founded a Benedictine Abbey at Penwortham, with monks coming from Evesham. After the Dissolution of the Monasteries, the monastic estate was sold to the Fleetwood family, who built a stately home known as Penwortham Priory. This was torn down in the early 20th century to make way for housing estates.
As for the church itself, it is primarily a 14th-century building, with the addition of a 15th-century tower in Perpendicular style. It is built of red sandstone and gritstone and features an ancient timber roof.
Of the numerous memorials, perhaps the most interesting is to John Horrocks, who was a prominent industrialist in the golden age of the Lancashire cotton industry and founded the textile company Horrockses, Miller, & Co.
The church stands in woodland, giving it the peaceful air of a rural building, despite the surrounding urban areas. The churchyard is accessed by way of a lych gate erected in 1896.
