The School was founded AD 1541 by King Henry VIII, in conjunction with the Cathedral Church of Chester. It was reorganised under the Endowed Schools Act in 1873, and by subsequent schemes of the Ministry of Education. The School is now Independent. The aim of the School is to prepare pupils for admission to Universities and the professions, and at the same time provide a liberal education.
