The history of Stonyhurst College as a school dates back to 1593 when its antecedent, the Jesuit College at St Omer, was founded in Flanders to educate English Catholics. The history of the present school buildings dates as far back as 1200 AD. The details of both are set out below.The earliest Deed concerning the "Stanihurst" dates from 1200 AD and can now be found in the Arundell Library in the College, whilst the earliest evidence of a building on the site is from 1372 when John de Bayley was licensed to have an oratory there; the archway in the Bayley Room, within the 'Blind Tower', is believed to date from the fourteenth century, and may well be the only remnant of that earlier building. The oldest portion of the extant buildings however, the Shireburn Mansion (Stonyhurst Hall), was founded by the Roman Catholic, Richard Shireburn, a descendant of the Bayley family, whose son attended the College at St Omers.
