and 5.5 m in height. The ceiling was supported by wooden beams with three central columns. The floor was paved with large stone slabs. This room, together with a smaller room to the north, were probably used for storage. On the first floor was the great hall of the castle in which banquets would have been held. It had the same dimensions as the ground floor storeroom but with a higher ceiling (6.5 m). It was lit by four large rectangular windows providing views over the Rhône valley. There were also three smaller windows to increase the ventilation, two facing west and one facing south. The walls were decorated with frescoes and a band of large red, bistre and black roses. A door at the north end of the hall opened into a well-lit smaller room with a chimney. The main entrance to the hall was on the east side near the donjon and close to the modern steps. The top floor of the building was lit by three large windows provided with benches and three smaller rectangular windows. The irregular pattern of the windows suggests that there were several rooms, perhaps apartments for the pope. The tiled roof with two equal slopes was entirely protected by the large outer walls. Tiles An archaeological excavation carried out in 1960 in the basement of the ruined rectangular building recovered a number of small glazed terracotta floor tiles. They date from the first half of the 14th century and would have originally decorated the main hall on the first floor. The tiles are square, 125–130 mm on a side and 20 mm in thickness. They are decorated in a Hispano-Moresque style which is more usually associated with dishes and jugs. Many have a plain coloured glaze, either green, yellow or occasionally black but some have designs in brown or green on a white tin glazed background. The tiles are similar to those discovered in 1963 on the floor of Pope Benedict XII's studium in the Palais des Papes. The room was built between 1334 and 1342 and is therefore a little later. The Châteuneuf tiles are slightly larger and often have animal designs. They were almost certainly manufactured in Saint-Quentin-la-Poterie. The papal accounts record large purchases of tiles in 1317. In 1994, a small archaeological excavation was carried out on the terrace at the foot of the southern façade of the papal
