The development, by means of great additions and alterations, of the present eastern arm and its magnificent crypt from the earlier and smaller Norman structures was probably taken in hand about 1190. The new work seems to have been begun from the east and continued westwards. It was at first perhaps roofed temporarily with wood, and only vaulted later. It may have been far enough advanced to allow of William of Perth’s burial, directly after his death in 1201, in the north choir transept (still called by his name), where his tomb and shrine were afterwards so much resorted to. On the other hand, his body may have been laid in the north choir aisle until the new transept was ready to receive it. This was probably not the case however; it certainly was not, if the conjecture be correct, that 1195 is the approximate date of the removal of the eastern half of the Norman undercroft and of the portion of the presbytery above it, and that a little work in the choir aisles had been done even earlier. Other authorities, though, incline to the opinion that the part of the Norman presbytery which projected into the new work was not removed before it was almost completely inclosed. This would put off its demolition till later.

The “whole choir” was, we read, rebuilt by William de Hoo, the sacrist, with the offerings at St. William’s tomb. The word “choir” must here, of course, be used in its more restricted sense, meaning the choir proper, as distinct from its transept and the presbytery. Even then to say absolutely that he rebuilt it is to go too far, for the walls dividing it from its aisles are still in the main of Norman construction, though they have Early English facings and decorations, and additions of this later period to their upper parts. The original intention of the architect had apparently been to change into arcades these solid walls, but, if so, he abandoned it. When the work on the choir walls was finished, some re-modelling of its aisles was soon carried out, buttresses being built within them to withstand the thrust of the new vaulting of the central part. In William de Hoo’s work at this time we must include the arches across the western ends of the choir aisles, with the one bay of the transept clerestory over the northern of them, and possibly also the choir arch, with the piers that carry it. It seems, however, that these piers were only finally freed from the Norman nave arcade, and completed, as we now have them, to be the eastern pair of supports to the central tower, by Richard de Eastgate about twenty years later. It is recorded that the new work had been roofed and leaded by the sacrist Radulfus de Ros and the prior Helias. The new choir was first used in 1227, when the monks made their solemn entry into it, and the works, that have been described above, must have been finished at that date. Some fittings, probably originally inserted at this early period, still remain, viz., the eastern side of the pulpitum and some woodwork preserved in the present stalls. Richard de Wendover, Bishop of Rochester, and Richard, Bishop of Bangor, dedicated the church, or rather its new portions, but it was not until 1240 that the ceremony took place.

We must now go back a few years in order to mention the great losses that the cathedral sustained in 1215. In that year King John besieged and captured Rochester Castle, stoutly held against him by William de Albinet and other powerful barons. Then, Edmund de Hadenham tells us, the church was so plundered that there was not a pyx left “in which the body of the Lord might rest upon the altar.” At such a time the offerings at St. William’s tomb, which have been alluded to above, were especially needed and especially acceptable.

Within the first half of the thirteenth century, but certainly several years later than the entry into the choir, further great works were begun by the monk and sacrist Richard de Eastgate. He probably commenced by clearing away the two eastern arches of each of the nave arcades, which, it will be remembered, are thought to have been continued right up to the choir arch; and, then, having completed the piers at the ends of the choir walls, laid the bases of the two others that with them support the central tower. He next began the new north transept (ala borealis versus portam beati Willelmi), and made it half as wide again as its slender predecessor. Afterwards the north-west tower pier was erected at the junction of the transept and the nave, and, finally, there is a discussion as to whether the northern tower arch was built now or not until later. We are told that all this work, begun by Richard de Eastgate, was almost finished by Thomas de Mepeham, who became sacrist in 1255. The laying out of the bases of the western pair of piers to the central tower was formerly assigned to a much earlier date; while the eastern piers were supposed to have been finally finished in William de Hoo’s time. This work would, however, scarcely have been done before the new wider transept was undertaken, and it cannot have been carried out before the eastern part of the Norman nave was cleared away.

Only a short time elapsed then before the building of the south transept (ala australis versus curiam) by Richard de Waldene, monk and sacrist, and next came the completion of the supports for the central tower, by the construction of its south-west pier and the other arches. The building of the eastern (the choir) arch, and the possible earlier date of the northern one, have already been spoken of. The two bays of the nave nearest the crossing, were also rebuilt in their present form, and the stability of the arches that were to bear the central tower was thus secured. The reconstruction of the whole nave seems to have been intended by the architects of this time; but want of funds, probably, stopped the work.

To leave purely architectural history for a while, we find the church on which all this labour was so lovingly bestowed undergoing another terrible experience in 1264. On Good Friday of that year it was desecrated by the troops of Simon de Montfort, after their capture of the city. In the old annalist’s account we read (in Latin) how they “entered the church of St. Andrew on the day on which the Lord hung on the cross for sinners.... Armed knights on their horses, coursing around the altars, dragged away with impious hands some who fled for refuge thither, the gold and silver and other precious things being with violence carried off thence. Many royal charters, too, and other muniments, in the Prior’s Chapel, and necessary to the church of Rochester, were destroyed and torn up. The oratories, cloisters, chapter house, infirmary and all the sacred buildings were turned into horses’ stables, and everywhere filled with the dung of animals and the defilement of dead bodies.”

There is a record of a later, more welcome visit from Earl Simon’s conqueror. In 1300 Edward I. made a progress in Kent, and we find the following items in the wardrobe accounts for this, the twenty-eighth year of his reign. On the 18th of February he offered seven shillings at the shrine of St. William, and a like amount again on the next day. He then went forward to Canterbury, and on his return from the archiepiscopal city gave, on the 27th of the same month, seven shillings each for the shrines of SS. Paulinus and Ythamar in the church of the Priory.
