Moulton Grammar School was founded through an endowment given in the will of John Harrox (died 1561) who was steward to Sir John Harrington of Weston. The School opened in 1562 with ten pupils and continued to educate boys until 1939 when it merged with Spalding Grammar School. Some school buildings still exist but are now private residences. John Harrox is commemorated in the name of the Primary School and the Moulton Harrox sports club. The Moulton Harrox Educational Foundation uses income from the management of more than to support the education of young people of the district.
