Harrow School is one of the world’s most famous schools. Founded in 1572 by a local yeoman farmer, John Lyon, under a Royal Charter granted by Queen Elizabeth I, it is located on a 324-acre estate encompassing much of Harrow on the Hill in north-west London. Around 830 boys aged 13 to 18, who come from all over Britain and across the world, live in the School’s 12 boarding Houses, and there are about 120 teaching staff and over 500 non-teaching staff.
