 The largest and most ornate tower (1899, by Bakewell) is based on Giotto's Campanile in Florence.The smaller ornate tower (1866, by Shaw) is styled after the Torre dei Lamberti in Verona.A third plain tower, built as part of Harding's final phase of expansion in 1919, is thought to represent a Tuscan tower house such as can be seen in San Gimignano.
