The Chapel of St John's College, unusual in being located on the first floor, was completed in 1863. The chapel has a plan that includes five bays. The two bays at the east end are distinguished as a chancel by a change in floor level. The eastern half of the chapel is in the traditional collegiate Choir arrangement. The details of the tracery and mouldings are late 13th and early 14th century English Gothic. There is a small gallery over the chapel, originally designed to enable invalids from the infirmary to hear Mass. The chapel is covered by a high wooden roof
