BEAUCAIRE.--Crossing the bridge of boats from the castle of King René, the bare limestone rock surmounted by the Castle of Beaucaire meets the view (Fig. 68). This castle was anciently a possession of the Counts of Toulouse. During the Albigensian crusade it was besieged by Simon de Montfort, and an interesting account of the siege operations _by himself_ still exists. While engaged in the siege he was attacked and defeated by Raymond VII. (1216). Although now a complete ruin internally, the walls exist all round and shew the great extent of the fortress (Fig. 67). The outer enceinte, and its long approach by wide flights of stairs from the west, can still be traced, as also the outline of the outer and inner bailey. The gateway of the latter, in a fragmentary state, still survives. The immense strength of the fortalice is distinctly apparent, owing to the height and steepness of the naked rock on which it stands (Fig. 69). [Illustration: FIG. 66. GATE OF TARASCON.] Almost the only defensive building in fair preservation [Illustration: FIG. 67. PLAN OF THE CASTLE OF BEAUCAIRE.] is the remarkable donjon which rises high above the walls. This tower (Fig. 70) is of the very unusual form of a triangle in plan; that shape having probably been adopted in order to fit a projecting spur of the rock. The basement floor (not accessible) was doubtless entered from a trap door in the floor above. It has no openings to the outside. The stair [Illustration: FIG. 68. CASTLE OF BEAUCAIRE FROM S.-E.] [Illustration: FIG. 69. CASTLE OF BEAUCAIRE FROM N.-E.] to the first floor is straight and is carried up in the thickness of the wall. The first floor forms a triangular hall with groined vault of peculiar form, has a fireplace in one angle, and is lighted with small loops. From this floor the staircase is carried up as a wheel in the south angle of the walls. The top floor has a segmental vault which carries the flat stone roof. This is formed of stone flags all overlapped and laid in regular courses, each slightly higher than the others as they rise towards the centre. [Illustration: FIG. 70. PLANS OF THE KEEP.] The staircase turret stands independently upon this platform, and has a sloping stone roof. The parapet is very perfect, and is, as usual, projected on bold corbels (Fig. 71). Owing to the sharp angles of the plan, the inclination of the corbels near the angles towards one another (in order to keep the arches over them as equal as possible) is much greater than usual--more marked than that, for instance, of the corbels at Avignon (above [Illustration: FIG. 71.
