A new school chapel, by the Scottish architect Maxwell Ayrton, was built between 1912 and 1916, and is now a listed building. The foundation stone of the chapel was laid by the chairman of governors, Sir Edward Busk, on 8 June 1912. The Chapel bell, cast in Whitechapel in 1915, is inscribed with the words "Ring in the Christ that is to be, Donum Dedit J. R. E.". The last words stand for "the gift of J. R. Eccles" (at the time second master, later headmaster), while the first eight are the last line of Alfred, Lord Tennyson's poem "Ring Out, Wild Bells" (1850). The Gresham family motto, "Fiat voluntas tua" ('Thy will be done') appears on the chapel's main door.
