Mackay writes about the large building in Block 22 (p. 152):
"At the floor level of the Late II Phase this building measured 51 feet 3 inches, North-South, by 56 ft. long at the north and about 54 feet 9 ins. at the south. The thickness of its walls indicates a building of some importance; indeed, the outer walls which have batter are 4 ft. 4 ins. Thick at the base and the inner walls 3 ft. 5 ins. Ledges and footings show that the building was repaired and its walls raised at various dates, though it does not seem to have been radically altered in design."
