The City of London School (CLS)is a boys' independent day school on the banks of the River Thames in the City of London. It is the brother school of the City of London School for Girls (a girls' school within the City).
The School was founded by a private Act of Parliament in 1834, following events starting from a bequest of land by John Carpenter, Town Clerk of London in 1442, for four poor children in the City of London. The original school was established at Milk Street, with the school moving to the Victoria Embankment in 1879, and then to its present site on Queen Victoria Street in 1986. Today, the school provides day education to about 900 boys aged 10 to 18 and employs approximately 100 teaching staff and around another 100 non-teaching staff including contractors.
