Church of England , Parish of St Mary, Harrow

In medieval times Saint Mary's was one of the most important churches in Middlesex. There is a twelfth-century tower with tall octagonal lead spires. The nave was re-built in the thirteenth-century when the rector was Elias de Dereham, the canon of Salisbury. Various additions and embellishments took place under John Byrkhead, rector from 1437 to 1468, then restored heavily in the nineteenth century. Many brasses including a small brass of John Lyons, founder of Harrow School.
