Construction of the chapel, originally intended to be slightly over twice as long, with eighteen - or possibly seventeen - bays (there are eight today) was stopped when Henry VI was deposed. Only the Quire of the intended building was completed. Eton's first Headmaster, <answer>William Waynflete</answer>, founder of Magdalen College, Oxford and previously Head Master of Winchester College, built the ante-chapel that finishes the Chapel today. The important wall paintings in the Chapel and the brick north range of the present School Yard also date from the 1480s; the lower storeys of the cloister, including College Hall, had been built between 1441 and 1460.
