This was a usual arrangement in similar castles of this period, as it was also in France and England. At Pierrefonds, for example, the keep is a large block, containing numerous apartments, and is sufficiently exten- sive to form an independent residence. It thus presents (as above pointed out) a striking contrast in the dispositions of its keep to that of Couci, which was erected about a century earlier, just as Doune contrasts with the Scottish keeps of the previous periods. FIG. 365. Doune Castle. Plan of First Floor. The entrance to the quadrangle is peculiar, being by an archway which passes below the great hall. The gateway is provided with wooden doors, strong iron-grated gates, which still exist, and a portcullis, which was worked from the window recess of the hall above. The gateway is flanked by a great round tower (Fig. 366), as at Pierrefonds. In the entrance passage there is a guard-room on one side, with a small prison entering from it, and on the other side are stores and cellars, and a well in the great round tower.
