Anthropology

Back in 1999. It was incredible- I went inside the smallest of the three Great Pyramids. The corridors were maybe 5 feet high; the ancient Egyptians were much smaller people than we are today!
I know they unearthed a fully intact river barge near the site, so maybe this discovery is another funerary offering of that sort. Or maybe it's something even cooler.

I hope you can find a way to go if you still really want to do it. It's a strangely humbling, even spiritual, experience. Though I must add that there is a Pizza Hut just down the road by the Sphinx- modernity does poke its crass face out, even in a place like that!
