A few years later the great western Tower with the wings, forming a second Transept, were begun, but whether by Bishop Harvey or by the monks themselves during the episcopate of Bishop Nigel (1133-1169), we cannot say; they were carried on during the episcopate of Bishop Ridel (1174-1189), and completed as high as the first battlements during that of his successor, Longchamp (1189-1197), producing a fine example of what is called the Transitional style. During this latter period the Romanesque had been rapidly giving way to the Pointed style, and thus as the building progressed one style merged into the other. After some years further progress was made towards the west, as the Galilee, or western porch, is stated to have been erected by Bishop Eustace (1198-1215), of whom it is recorded that "he built from the foundation the new Galilee of the Church at Ely, towards the west, at his own cost." "This has given rise to much difference of opinion. Some persons think that by the 'Galilee towards the west,' is meant the western porch, while others holding that so fine a work is inconsistent with so early a date, suppose the Galilee to have been the northern half (now lost) of the western Transept.... My own impression has always been that it was the west porch which still exists."[7] Be this as it may, it is a beautiful specimen of the Early English style; and Bishop Northwold (1229-1254) took down the east end of the church and lengthened it by the six eastern arches, usually called the Presbytery, with its magnificent eastern facade, in the same style; they were begun A.D. 1234, and finished and dedicated in 1252, being "one of the noblest pieces of architecture of that glorious architectural period." About the same time a spire of timber covered with lead was erected on the Tower. [Footnote 7: Lecture on Ely Cathedral by the late Sir G.G. Scott, at the Etheldreda Festival, Oct. 1873.]
