In the small mound excavated at Sakje-Geuzi, the form of the main enclosure was found to be practically rectangular and four-sided, enclosing an area about a hundred feet long and eighty feet wide. A slight modification in form seems to have been made, either at the time of building the whole wall or later, where the north-western wall skirts the steep edge of the mound as it approaches the northern corner. No gateway was found, the lower side of the mound opposite the palace being almost denuded even to the foundations of the wall, which was found, in other places, six or eight feet below the surface. Nor did any outer rampart on the lower level correspond to the wide enclosure at Sinjerli. The wall was built of small stones revetted together by stouter facing blocks; these, though laid approximately in courses, were fitted together without much shaping and without mortar, as in Beuyuk Kaleh at Boghaz-Keui, and in the fortifications of Sinjerli. The wall was supported by external buttresses or mural towers, about thirteen feet wide, and projecting about three feet; these occur at intervals which decrease considerably around the steeper edge of the mound. The corners were similarly strengthened by rectangular turrets of the same projection. The wall was nearly twelve feet thick, and its foundations were proportionately deep and massive, as though destined to sustain a height of twenty feet or more, of which some thirteen feet remained preserved where the soil was deepest. The lowest courses of the foundations were built of large stones, suggestive of the masonry on Beuyuk Kaleh at Boghaz-Keui.[683]
