When you look up at the Great Pyramid, it’s apex is missing. It is flap topped and not pointed like a pyramid should be. Usually, when a pyramid was constructed, the top part, or capstone (also called top-stone), was the last thing to be placed on it. It was considered the most important part of the pyramid and was made of special stone or even gold. The capstone was usually highly decorated.
Was the great pyramid always without a capstone or was it stolen, destroyed, etc? No one knows but the accounts of visitors to the pyramid from the ancient past (as far back as the time of Christ) always reported that the pyramid lacked a capstone. It is possible that it was never finished. Another possibility is that capstones were sometimes made of gold and maybe the first thing looted. The only problem is that this would be a very large capstone. If you climbed to the top, you could walk around very freely on the pyramid as many have done. It is about 30 feet in each direction. Thus, this capstone would have been huge and weighed a tremendous amount. Also on the summit you would see something that looks like a mast or flagpole. Actually it was placed there by two astronomers in 1874 to show where the Pyramid’s actual apex would have been if finished.
