[3] St Mary's was originally the parish church of the Hundred of West Derby and of the area containing what was to become the city of Liverpool.

[5] None of this has survived, the oldest part of the present church being the west tower, which was built in 1829–32 to a design by John Broadbent, a pupil of Thomas Rickman.

[7] The body of the church was rebuilt between 1947 and 1953 by Quiggin and Gee, retaining the exterior as before, but creating a new interior.

[8] It is now open to visitors to allow them to view aspects of the church that date back to the Norman era.

In the chapel is a reredos that includes a copy of the Deposition of Christ by Fra Angelico, executed in 1860 by Vincenzo Corsi; this was formerly in Haigh Hall.

The font was broken into pieces in 1941 and restored by E. Carter Preston, who also designed the stained glass in the church.
