College, the home of the Queen’s Scholars and the oldest house at Westminster, was effectively founded in 1560 when the school’s charter stipulated that there should be 40 Queen’s Scholars. Special weight in their selection was to be given to ability, good character and poverty. To become Scholars, boys had to pass an oral examination known as ‘The Challenge’, which shifted to paper in 1856.
Scholars had special privileges not accorded to other boys, such as the right to enter the Palace of Westminster.
The Scholars include John Dryden, the first Poet Laureate (1631-1700); John Locke (1632-1704), the empiricist philosopher; A. A. Milne (1882-1956), creator of Winnie-the-Pooh; and Kim Philby (1912-1988), of the Cambridge spy ring. The first female scholars were admitted to College in 2017.

Grant's was opened as an independent boarding house by Mrs Margaret Grant, or Mother Grant I, in 1749, when keeping boarders was one of the few respectable occupations for middle-class women. The house continued under the Grants’ management until Mrs Dixon, the last of the family, sold the building to the then housemaster, Charles Alfred Jones in 1868. As well as income from the sale of the house, Mrs Dixon also had a share of the profits of Dixon's antibilious pills, the world-famous 'pill to cure all ills'.

Many traditions survive at Westminster, but one that has been discontinued at Grant’s is the custom that saw new boarders ‘walk the mantelpiece’ in Hall. Lawrence Tanner, a pupil who kept a thorough diary of his time at Westminster, records his own experience of walking the mantelpiece here.

Grantites of particular interest include Lord John Russell (1792-1878), a Whig and Liberal Prime Minister and keen reformist; Charles Longley (1794-1868), Archbishop of Canterbury; Edgar Adrian (1899- 1977), winner of the Nobel Prize for Physiology; the actor John Gielgud (1904-2000) and Dominic Grieve MP (1956-).
