postern, with its movable bridge, double machicolations, loop-holes, portcullis, and gates. Even within this, the entrance to the castle was impeded by a sloping and turning passage, furnished with numerous doors, and rising for twenty-three feet before the level of the courtyard was reached.
Such defences were almost impregnable, and are a good illustration of the intricacy of the fortifications adopted at that period. At a later time such contrivances were found to be a mistake, as they impeded the movements of the garrison. They proved a weakness rather than a strength by preventing men from being moved rapidly to a critical point at the required time. The leading idea, at this period, was to render every point of the defences independent of the rest. Each tower is, therefore, a separate fort; the castle and barbican are independent of the city walls, and could hold out although the town was in the hands of the enemy; and within the castle there are two independent towers or donjons, which might still form a refuge for the garrison for some time after the castle was taken.
The lofty square tower (see [Fig. 110]), which was crowned with a bretêche, was carried up to a sufficient height to dominate the town and the whole surrounding country. This structure and some of the adjoining walls date from the twelfth century. The other buildings on the north side of the castle are of the time of St Louis. The inner enceinte of the castle with its towers and gates built by Philippe le Hardi (the latter part of the thirteenth century) are splendid examples of the military works of the period.
The walls of the towers surrounding the town are built with solid masonry in regular courses, with the face left rough. The lower part of the curtains is pierced with the long loops, sometimes 11 or 12 feet in length, then in use, and the top was fortified with hoardings or projecting wooden galleries, from the floor of which the defenders could drop stones and other missiles on the assailants, so as to keep them off from the base and prevent mining. All the walls and towers were furnished with these hoardings. The square holes in which the beams were inserted for carrying the galleries are still visible both in the outer and inner walls (Figs. 110-113).
The towers are placed at suitable intervals to enable the curtains to be defended from them by lateral fire, and some of them are strengthened with a projecting beak to prevent the sappers from approaching when the angle could not be well commanded from the adjoining parapets, as is the case in the tower at the N.W. angle of the walls seen in [Fig. 111]. One large square tower (shown in [Fig. 111]) called the “Tour de l’Evêque” joins the outer and inner enceintes together by bridging over the space between them. It has thus complete control over the lices both from apertures in the vault, and from the hoardings which were projected on the flanks. This tower derives additional interest from having been used by Viollet-le-Duc as his studio while superintending the work of restoration, and it contains a number of fine plaster casts prepared by him.
The parapet walk of the inner wall runs all round the battlements. In some cases it is interrupted by the towers ([Fig. 114]), and passes through them; in other cases it is carried round the exterior of the towers on the side next the town,—the former towers being posts for guards and sentinels, and the latter being intended to serve as independent posts for defence. Access to the walls is provided by good open stairs on the side next the town, as shewn in [Fig. 114], which represents the interior of the walls at the same place, as [Fig. 113] shews the exterior.
