You’ve seen them a thousand times in pictures. But it’s surreal to stand before them, up close, in all their grandeur and glory. The Great Pyramids are the only remaining wonder of the ancient world, and they certainly invoke awe. Their sheer size dominates all that’s around them, including the modern buildings. And beyond their pure audacity, great mystery still surrounds them. How were they built, and why? They defy logic and comprehension—you feel it while standing before them. The Great Pyramids of Giza may be overrun by the machinations of mass tourism now, but the visitors come for a reason: they are one of the most incredible sites in the world, and by themselves justify a trip to Egypt.
