Hole # 2 (right hole): The hole was made by breaking the cement, most likely with a large hammer, and cutting one end of 3 reinforcing iron rods with a hack-saw before bending them. The hole measures 60 cm. X 50 cm. (2 ft. X 1 ft. 8 "). At this location the roof has collapsed to within 45 cm. (1 ft. 6") of the broken cement lying on the ground. Had the dark hole existed in 1944, it would have been visible in air photos, which it is not.
