The Triptych was placed above the altar in 1909, and is made up of 32 panels with carved scenes of the Passion, with portraits of the saints and scenes from the bible at the sides. At the top, Our Lady and St John stand at the side of Jesus on the Cross (John 19:26).
It was designed by Sir Giles Gilbert Scott, whose many significant works include the Albert Memorial in London.
The Triptych was removed in the 1970s, as the church was altered in the liturgical reforms of that time. It was restored to its original position in the reordering of 1995.
