Gresham's School is a public school (English independent day and boarding school) in Holt, Norfolk, England, one of the top thirty International Baccalaureate schools in England. The school was founded in 1555 by Sir John Gresham as a free grammar school for forty boys, following King Henry VIII's dissolution of Beeston Priory. The founder left the school's endowments in the hands of the Worshipful Company of Fishmongers of the City of London, who are still the school's trustees.
