On a site on the opposite side of the river Ribble to Preston stood the priory of Penwortham. Its situation was picturesque, commanding as it did an exclusive view down the valley, through which the river flowed, and not far from it were the parish church and castle. It was founded as a dependent upon the abbey of Evesham, in the county of Worcester, in 1087, by two brothers, Warine and Albert Busset, with the approval of Pope Alexander III., and it was for 400 years regularly supplied with monks from the parent house. The monks were Benedictines, or black monks, and their home in Lancashire was but sparsely endowed, although it included the churches of Penwortham, Leyland and North Meols. At the dissolution it was rated at a little over £100. No great number of churches were erected in this hundred during several succeeding centuries. In Blackburn Hundred two churches are named in the Survey--St. Mary's at Whalley and St. Mary's at Blackburn--and the only other parish at all likely to have had a church earlier than this period is Ribchester. The present church is dedicated to St. Wilfrid, and tradition adds that its original foundation was laid in Saxon times; it certainly is built close to the walls of the ancient Roman castrum (see p. 27). Another very early foundation was that of Chipping, said to have been built in 1041. St. Mary's of Blackburn is still the parish church, but there is no evidence to prove that its foundation dates back to pre-Norman times. The church at Whalley is perhaps the most interesting church in Lancashire, not only from its undoubted great antiquity, but from its association with the abbey, which was second only to Furness in importance, but about the history of which much more is known.
