Avignon was thus occupied by the Popes from 1316 to 1376, or sixty years, during which time there reigned six Popes. They were all Southern Frenchmen, a circumstance which probably had considerable influence on the style of the architecture, which is undoubtedly quite that of Provence, and has small affinity with the style then in use in Italy, notwithstanding that the name of the architect Obreri sounds somewhat Italian. The construction, mouldings, vaults, and defences, are all in the style of Southern French work, and do not recall Italian features. The only Italian details are the paintings on the vaults and ceilings, said to have been executed by Giotto and Simone Memmi. Of these there are unfortunately only a few fragments left. The vault of the great Consistorial Hall was completely painted, but the building having been cut up into several floors in order to convert it into barracks (in which occupation it still remains), the faded and damaged condition of the paintings can well be conceived.
The Anti-Popes Clement VII. and Benedict XIII. occupied Avignon from 1379 to 1403. The latter was besieged in the palace by General Boucicaut in 1398. The Pope fled, but the palace did not capitulate till 1411. The buildings suffered severely from fires which occurred in 1378 and 1413.
The principal entrance to the palace is on the west side, and opens from an esplanade which commands the surroundings, and was formerly divided into several baileys or courts, with walls, towers and gates. The entrance gateway was defended with two portcullises, with folding gates and double machicolations. It had originally an advanced work in front, which was replaced in the seventeenth century by a crenellated wall. The appearance of the building, whether it be regarded externally or from the courtyard, is grand and imposing from its vastness and height. The towers and walls are, even in their present crippled condition, most commanding from their magnitude, the former being about 150 feet in height, while the walls rise to about 100 feet. On entering the great courtyard (D), evidence presents itself of the difference in level between it and the older northern court (C), in the rugged foundation on which the south front of the latter stands, the rock having been cut down, as above mentioned, to the level of the lower court. The frowning machicolations of that side, which look somewhat out of place in a Cour d’honneur, are explained when we remember that under Pope Benedict XII. this formed the exterior of the south face of the palace, before the south courtyard was added by Clement VI. and Innocent VI.
The most striking feature of the architectural details of the palace is the machicolations of the parapet. These consist in long grooves opening between the inside of the parapet and the external face of the walls, the parapet being carried on pointed arches thrown between buttresses which project at intervals (see [Fig. 47]). This form of machicolation (which we have already observed at Cruas) is much used in the southern provinces, perhaps from the prevalence of such works in the churches, most of which were fortified, and where the buttresses which existed for other reasons, were found convenient, and were thus utilized. These long machicolations have the advantage of allowing beams, and other lengthy missiles to be thrown down on assailants; but the frequently recurring broad buttresses or wall spaces, which have no defence immediately over them, are a drawback.
In the North these long grooves are very rarely used; a continuous series of machicolations between bold corbels being the form almost invariably preferred. At Avignon the towers were crowned with the latter kind of defences, as the relics of the broken corbels still shew.
The Cour d’honneur communicates freely with every part of the structure. To the right, on entering, is observed the arcade which contains the great staircase leading in two flights to the principal apartments on the first floor. Two posterns open from this courtyard, and these are carefully masked in the re-entering angles by buttresses, and defended with a portcullis. A staircase also leads to the upper courtyard.
The most ancient part of the palace is the Tour de Trouillas, at the north-east angle, an immense mass which towers above all the other works and formed the Keep.
The Pope’s apartments in the time of Urban V. were on the first floor of the buildings surrounding the Cour d’honneur. From the landing of the great staircase, which gave access to the principal apartments, passages were carried round the building in the thickness of the wall next the courtyard. These were carefully constructed and finished with pointed and groined vaults. They communicated with the various rooms, and also with several staircases which connected the different floors, and led to the defences on the roof. The apartments of the south court were also joined to those of the north court by these passages. The great kitchen was situated on the first floor of the building next the keep. It has a high pyramidal vault, which gives it a mysterious look, and perhaps led to its being long regarded as the chamber of torture and hall of execution of the Inquisitors. The banqueting hall was in the north court, near the kitchen and the keep. The smaller tower (M) in the centre of the east flank (now called the Salle de la Justice) contains in two floors some admirable paintings of the fourteenth and fifteenth centuries, which are in a fair state of preservation.
The entire building is of the most massive masonry—the whole of the basement being vaulted and constructed so as to defy destruction.
Commencing with the great keep at the north-east angle, and proceeding round the palace by the west, south, and east, the towers occur in the following order:—north-east—Tour de Trouillas; north-west—Tour de la Gache, followed by the Tour de St Jean, Tour de St Laurent, Tour de la Cloche, Tour des Anges, Tour d’Estrapade.
