The whole building, according to Professor Willis, is full of peculiar fancies, which all appear to be characteristic of a school of masons who were extremely skilful, and glad of an opportunity of showing their skill. The mediæval masons, he thinks, were "perfectly practical and most ingenious men; they worked experimentally: if their buildings were strong enough, there they stood; if they were too strong, they also stood; but if they were too weak they gave way, and they put props and built the next stronger." That was their science—and very good practical science it was—but in many cases they imperilled their work, and gave trouble to future restorers.
The arrangement of the buildings differs in one very essential point from almost every other in the kingdom. The cloisters and the claustral buildings were, as a rule, on the south side of the church, for the sake of shelter, and also of sunshine. At Gloucester they are on the north side of the church, the reason being (according to Mr Fosbroke) that when Aldred laid the new foundations farther south, the cloisters found themselves on the north side.
Dallaway has said very truly that "Few churches in England exhibit so complete a school of Gothic in all its gradations from the time of the Conquest as the Cathedral of Gloucester." This is true with the exception that of "Decorated" architecture there are but few examples, and it is probable that very little new work was done in connection with this cathedral until the monastery became vastly enriched by Abbot Thokey's policy in causing the body of Edward II. to be brought from Berkeley Castle for interment in his abbey. It is said that the amount of offerings made at the tomb during the reign of Edward III. was enough to have entirely rebuilt the abbey. In consequence of this the Cathedral is full of some of the finest examples of the styles known as "Transition from Decorated to Perpendicular" (anticipative Perpendicular) and pure "Perpendicular"—a style which, in Professor Willis's opinion, originated at Gloucester. From every side there is something to interest the careful observer.
As a rule, visitors see it first from the south side, and the south-west general view is one of the best, equalled, but not surpassed, by that from the north-west. The north view from the Great Western Railway, with the school playing-fields in the foreground, makes a striking picture, but it is more sombre than the picture formed by the south front. Viewed from the north-west corner of the cloister-garth, the pile is seen perhaps at its best. From this point it is easy to study so much of the varied architecture of the whole, and with little effort to transport the mind back for a space of four hundred years. The eye first rests upon the turf of the garth, now tastefully laid out after many years of comparative neglect. Flanking the garth on every side are the exquisite windows of the Cloister—a cloister which no other can surpass. Above the Cloister will be seen on the eastern side the sober, impressive Norman work of the Chapter-House in which so much of our English history has been made. To the south of this is the Library, built close against the walls of the north transept, which tower above, and lead the eye upward to the great tower which, "in the middest of the church," crowns the whole.
