HIGH WONDERGreat Pyramid of Giza
How did Fourth Dynasty Egypt, without iron tools, pulleys, or the wheel, quarry, transport, and stack roughly 2.3 million stone blocks — some weighing over 50 tonnes — into a structure aligned to true north within a fraction of a degree, and which exact ramp or lifting method got the largest blocks into place?

Great Sphinx of Giza
How did Old Kingdom Egyptians carve the largest monolithic statue of antiquity — a 73-metre human-headed lion — in place from a single limestone ridge, and why, four and a half thousand years later, can we still not name with certainty the pharaoh who ordered it?

Valley Temple of Khafre
How did Old Kingdom builders quarry, move, and raise local limestone core blocks weighing 100 tonnes and more — then sheath them in red granite cut to joints so tight, and so cleverly interlocked around the corners, that a knife blade will scarcely enter — using only copper tools, stone pounders, sledges, and earthen ramps?
