The clearing away of galleries, the provision of new seating and the renewal of much window tracery have been the principal changes, the greatest loss being the destruction of the Corpus Christi Chapel. The nave is of moderate width and consists of only four bays, the eastern arches being narrower and made to abut against the tower after the manner of flying buttresses. The columns are clusters of four large filleted shafts separated by small ones while the bases are high and evidently meant to be seen above the benches. The caps are shallow and very simple, while the shafts of each pier reappear as part of the arch moulding.
