The charity known as the Friends of St Mary’s was founded in 1945. It comprises a group of people - from Harrow and further afield - whose prime objective is ‘to help preserve and improve the fabric and precincts of St Mary’s, Harrow on the Hill, and to bring together in association, all who may wish to do so.’ Their interest is the preservation of the ancient and important church whose spire has been the landmark of the borough for centuries.
