John Lyon's Foundation

The original school endowed by John Lyon in 1572, Harrow School is a full-boarding school for boys aged 13-18, located in Harrow on the Hill, northwest London.

An independent day school for boys and girls, John Lyon School opened originally in 1876 to preserve John Lyon’s original aim to educate boys local to Harrow on the Hill, as Harrow School’s pupils increasingly came from further afield.

Using the income from John Lyon’s original trust, John Lyon’s Charity (charity number 237725) awards grants to promote the life-chances of children and young people living in the nine boroughs through which the two roads between Harrow and London pass.
