The church is rectangular eith a nave and two aisles, and is the largest city parish church. Much original glass survives ; part of the east window dates from 1330. The pillars show Henry's crown and keys or crossed ewords, the symbols of St Peter and St Paul. The higher windows (the clerestory) and a false West front added around 1600. The dark marble slab in the main aisle is probably an old Minster altar table brought here in 1617.
