 the citadel wall. Since the Tower VI g contains some remains of its original brick superstructure, we are led to infer that it is older than the Towers VI h and VI i, which show no trace that their upper wall was ever built of anything but stone.

 We have seen that the great rectangular Tower VI i (fig. 16) was erected later than the bastion (s p t u), and that it projects from a part of the city wall which is only 2.20 m. thick. Within the tower has been found an inner room 5.70 m. long and, in the center, 5.30 m. broad. A door (a), which in later times was walled up, opened on the north. The purpose of the foundations (q) is not known, since they are not near enough to the center of the inner room to serve as a base for a supporting pillar. The sides of the tower are of varying thickness. The front wall is 4.40 m. broad, while the side walls are not over 2.20 m. The right wall, forming an angle at k, bulges out to a greater width, thus furnishing stronger protection for the corner (g) of the city wall on the east of the Gate VI T. The tower walls are preserved only to a height of 2 m. Consequently we can get no conception of the upper structure of either the gate or the tower. Two very remarkable stones (m n in fig. 15), the purpose of which is unknown, are situated before the front wall of the tower. There can be no doubt that they must he assigned to the VI City.
