I remember the old interior of St Werburgh's and it was very different from what is there today. The sanctuary was very classical in style, flanked by gianr pilasters, but what I remember most was the full set of apostles. These were life size statues of the 12 apostles (by Mayer of Munich) arranged around the church on plinths about 12 foot above the floor.
The church was "modernised" in the late 1960s due, it is said, to a massive infestation of dry rot.
The church, following the re-0rdering, has been described by the North West Catholic History
Society as:"An expanse of pastel pink reminiscent of a night club circa 1970 and an abundance of timber that would be more at home in a sauna or leisure centre."
I have not seen any pictures of the old interior, but the Diocesan Archives may well have some.
