The pyramid was then a dummy, made of rubble within a revetment of heavy flint nodules, which was faced with fine limestone. It was erected on a pyloni-form base with heavy cornice of the usual Egyptian pattern. This central pyramid was surrounded by a roofed hall or ambulatory of small octagonal pillars, the outside wall of which was decorated with coloured reliefs, depicting various scenes connected with the _sed-heb_ or jubilee-festival of the king, processions of the warriors and magnates of the realm, scenes of husbandry, boat-building, and so forth, all of which were considered appropriate to the chapel of a royal tomb at that period. Outside this wall was an open colonnade of square pillars. The whole of this was built upon an artificially squared rectangular platform of natural rock, about fifteen feet high. To north and south of this were open courts. The southern is bounded by the hill; the northern is now bounded by the Great Temple of Hat-shepsu, but, before this was built, there was evidently a very large open court here. The face of the rock platform is masked by a wall of large rectangular blocks of fine white limestone, some of which measure six feet by three feet six inches. They are beautifully squared and laid in bonded courses of alternate sizes, and the walls generally may be said to be among the finest yet found in Egypt. We have already remarked that the architects of the Middle Kingdom appear to have been specially fond of fine masonry in white stone. The contrast between these splendid XIth Dynasty walls, with their great base-stones of sandstone, and the bad rough masonry of the XVIIIth Dynasty temple close by, is striking. The XVIIIth Dynasty architects and masons had degenerated considerably from the standard of the Middle Kingdom. This rock platform was approached from the east in the centre by an inclined plane or ramp, of which part of the original pavement of wooden beams remains _in situ_.

To right and left of this ramp are colonnades, each of twenty-two square pillars, all inscribed with the name and titles of Mentuhetep. The walls masking the platform in these colonnades were sculptured with various scenes, chiefly representing boat processions and campaigns against the Aamu or nomads of the Sinaitic peninsula. The design of the colonnades is the same as that of the Great Temple, and the whole plan of this part, with its platform approached by a ramp flanked by colonnades, is so like that of the Great Temple that we cannot but assume that the peculiar design of the latter, with its tiers of platforms approached by ramps flanked by colonnades, is not an original idea, but was directly copied by the XVIIIth Dynasty architects from the older XIth Dynasty temple which they found at Dêr el-Bahari when they began their work.
