Originally the church consisted of a single nave, without aisles, vaulted with a pointed barrel-vault, strengthened with transverse ribs and internal buttresses, being, as above explained, one of the arrangements common in Provence. The east end terminated with an apse, the bay in front of which is vaulted in a remarkable manner. A dome is frequently introduced in this position; but in the present instance, owing to the width of the bay being small compared to the width of the church, a square space on which to raise the dome could not readily be obtained.

accomplish this, successive arches are thrown across between the transverse ribs, rising with the curve of the latter and advancing over one another, till the central space becomes a square, on which a lantern, with eight Roman-looking columns, is raised and supports an octagonal dome above.
In the twelfth century the rock, on the summit of which stands the Church of Notre Dame des Doms, was covered with habitations and gardens, which were dominated by the ancient castles of the Podestà and the Bishop. Pope Clement V., on his first arrival at Avignon, occupied the Convent of the Dominicans; and John XXII., in 1316, lived in the building which existed in his day where the Pope’s Palace now stands. In 1336 Benedict XII. demolished what his predecessors had erected, and rebuilt the northern part of the existing Palace (Plan, [Fig. 49]—from Viollet-le-Duc’s Dictionnaire), being the side next the Cathedral, on a grand scale, from plans by the architect Pierre Obreri. His works terminated at the “Tour de Trouillas,” or the great donjon (B) at the N.-E. angle, and is marked by another immense tower (B) at the west end of the range, called the “Tour de la Gache.”
The south face (E) of the northern courtyard, and the southern walls of enceinte were constructed under Pope Clement VI. It was also he who acquired the suzerainty of Avignon and the Comtat Venaissin from Queen Jeanne in 1347.
The southern front of the palace was completed by Pope Innocent VI., including the great Chapel, or Consistorial Hall (G), a building about 170 feet long by 50 feet wide, roofed with pointed and groined vaulting. The great tower (H) adjoining to the south contains the sacristy, &c. Urban V. levelled the space which forms the Cour d’honneur (D), excavating the platform out of the solid rock. Owing to the slope of the ground, this court is about one story lower than the older northern court.
The same pontiff further erected the east wing, and added the seventh tower, called the Tour des Anges. Gregory XI. left Avignon and returned to Rome in 1376.
