 Built to accommodate just over 100 people, it long ago became too small to accommodate the whole school (currently 690 boys).Additional seating installed in the re-ordering and extension carried out by the Victorian architect Butterfield allows the chapel to seat 320 people.On Sundays half the houses worship in Chapel, while the other half worship (at the same time) in St Michael's Church (known as "Michla"), a redundant parish church central among the boarding houses, which the College took over in the last century.
