HOLES IN WALLS OTHER THAN DRAINS
This peculiar feature of ancient architecture is especially prominent at the Acropolis, also in East Ruins, and in almost all the ruins in the Valley of Ruins. There are holes, generally square, in the lower parts of the walls at two or three feet above any ancient floor. They are found only on the inside faces of walls, not one as yet having been discovered on the outer face. That they are intentionally made is a matter of ocular demonstration, for many have lintels either of large granite slabs or of slate beams. The blocks of the side framings are all built flush with each other. Their peculiarity is that they do not extend back into the wall for more than the length of a block, in one case of two blocks, and the internal packing blocks in the wall are seen inside. One such recess on the Acropolis shows traces of having once been lined with granite cement. The bottom portion of a similar recess in Upper Passage also has remains of cement lining. The largest recess is to be seen on the west side of a divisional wall in East Ruins. This is 3 ft. high and 1 ft. 10 in. wide. No such recess has so far been discovered in the Elliptical Temple, but at least fifty have been found elsewhere among the ruins.
