The tower having been much injured and weakened by fire, a new one, according to Blomefield, was begun and finished by Bishop Ralph de Walpole; but this, says Britton, more properly applies to the spire, the style of which, rather than of the tower, corresponds with that period. Bishop Walpole ruled the diocese from 1289 to 1299. Before his translation to Ely, which took place in the latter year, he commenced the cloister at the north-east angle, and built the chapter house. He only completed a small portion of the east aisles. The chapter house has since been destroyed. The rest of the cloister was built by Richarde de Uppenhall, Bishop Salmon, Henry de Will, John de Hancock, Bishop Wakering, Jeffery, Symonds, and others, and was completed A.D. 1430, in the 133rd year from the first commencement of the work. In January, 1362, the spire was blown down, and the choir thereby much injured; but under the auspices of Bishop Percy, the present spire was erected and the choir repaired. In 1629, the upper part of the spire was again blown down, and in 1633, at a general chapter, it was ordered to be repaired. In 1843, seven feet were added to its elevation, with the present finial which formed a consistent termination to the crockets. In 1463, the church was much injured by fire, the wood work in the interior of the tower having been ignited by lightning. Under Bishop Lyhart, however, it was again repaired and ornamented. The splendid stone roof of the nave was added, the cathedral was paved, and a tomb was erected over the founder, which was afterwards demolished during the great rebellion. About the year 1488, Bishop Goldwell built the roof of the choir of similar but inferior work to that of the nave, adding the upper windows and flying buttresses. He also fitted up the choir and the chapels around it, and covered the arched stone work with lead. In 1509 the transepts having been much injured by fire, Bishop Nykke repaired them, adding stone roofs to them in the same manner as the rest of the church. At the dissolution of the monasteries, the cathedral suffered greatly from the zeal of the Reformers, much curious work being destroyed; and several obnoxious crucifixes, images, niches, tabernacles, and paintings, were removed. In 1643, the fanatics took possession of the church and the adjoining palace, and plundered them of all that was valuable. The Yarmouth people being in want of a workhouse, sent a petition to the Lord Protector, praying that “that great useless pile, the cathedral, might be pulled down, and the stones given them to build a workhouse.” Of course the petition was not granted. Soon after the restoration, the church was fitted up again. In 1740, the nave and aisles were newly paved, the tower was repaired, and the church cleaned. In 1763, the floor of the choir was again repaved, the stalls repaired and painted, and other improvements made, not always in harmony with the original structure.
