Eton and Harrow are public schools (private fee-paying schools in Britain) attended by the children of the wealthy and powerful. Harrow and Eton play an annual cricket match at Lord's.
Eton College was founded by King Henry VI in 1440. David Cameron is one of many old Etonians to become Prime Minister.
Harrow School, established in the sixteenth century, has also produced Prime Ministers. The most notable is Winston Churchill, who discusses his experience of public school in his book My Early Life.
