Pretty big, in case you were wondering. Here is a photo of Egypt’s Great Pyramid of Giza, which checks in at 480-feet and was the tallest structure in the world for several thousand years after it was constructed.
And here is a close-up view of the same pyramid, with me standing at the base and the rocks all around me going up, and up, and up…
How exactly did they construct this 4,000 years ago? It’s mind-boggling.
