 he third great construction phase was begun during the last years of Philippe III le Hardi's reign (1270-1285) and the beginning of Philippe le Bel's reign (1285-1314), in order to modernise a fortress that had become the symbol of royal power on the border between France and Aragon. Benifiting from the royal engineers' skills, the ancient inner wall which had previously been restored between 1226 and 1239 underwent major reconstruction. The new masonry work in bond with bossing contrasts with the facing of the old wall. The south west corner and the area between the Narbonne Gate and the curtain wall facing the Moulin du Connétable Tower were rebuilt. However, the decision was taken to preserve the ancient fortification on the south and north sides but repairs had to be made to some of the facings and parts of the footing. On the north east side the ancient perimeter was abandoned in only one section in order to raise the curtain wall that joined the Trésau and Moulin du Connétable towers. The line of defence was completed with circular towers except for the Saint-Nazaire and Bishop's Towers which were square. A great many of these towers were rebuilt on the foundations of ancient towers. The Trésau Tower and the Narbonne Gate were erected on the eastern facade. They are remarkable examples of Gothic architecture which combined military ingenuity, comfort and sumptuous decoration.
