The first work undertaken by Pierre was the enlargement of the papal chapel of John XXII. This was doubled in length, and the lavish decorations executed by John's master painter, Friar Pierre Dupuy, were continued on the walls of the added portion; payments for white, green, indigo, vermilion, carmine and other pigments, and for colored tiles, testify to the brilliancy of its interior. Meanwhile work was proceeding on the massy new tower, the Turris Magna, now known as the Tour des Anges, the best preserved of all the old towers. The foundations were laid on April 3, 1335, and it was roofed with lead on March 18, 1337. The basement formed the papal wine-cellar; the ground floor was the treasury, or strong room, where the specie, the jewels, the precious vessels of gold and silver and other valuables were stored; many payments are recorded for locks and bars and bolts for their safe-keeping within the ten-feet-thick walls of the tower. The next great work put in hand was the east wing, which was raised on a space left by John's demolished, or partially demolished, structure. On November 20, 1337, two masons (lapiscidarios), Pierre Folcaud and Jean Chapelier, and a carpenter, Jacques Beyran, all of Avignon, contracted to carry out the plans of a new architect, Bernard Canello, for the completion of Benedict's private apartments, and on the same day Lambert Fabre and Martin Guinaud, housewreckers, were paid eighty-three gold florins on account, for the demolition of the old buildings. This wing, since wholly remodeled by the legates and the modern corps of engineers, comprised the papal Garde Robe, the Garde Meuble, the private kitchen and offices and, on the floor above, the papal dining-room, study and private oratory. The walls were, of course, embattlemented, and in 1337 the most exposed portions of the new buildings were defended by a stout rampart.... The whole ground floor, 110 feet by 33, was occupied by a great reception hall (Camera Paramenti), where distinguished visitors were accorded a first welcome before being admitted to a private audience, or accorded a solemn state reception in consistory, as the import of their embassy demanded. The popes were also used to receive the cardinals there, and two doorkeepers were appointed who must be faithful, virtuous and honest men and sleep in the hall; their office being one of great trust, was highly paid, and they were generally laymen. It was probably in this hall that St. Catherine was received by Clement VI. The Avignon conclaves were held there, for on December 31, 1352, four hundred and fifteen days' and nights' labor were employed in breaking down the walls between the dining-hall and the Camera Paramenti, clearing away the stones and making secret chambers for the lord cardinals, in which chambers were twenty-eight cells....
