The Pyramid of Cestius in Rome is worth seeing, but maybe not worth going to see. Cestius was an ordinary rich guy back who was caught up in the rage for things Egyptian that evidently gripped Rome in the late first century BC, so he built this tomb for himself, around 12 BC (of course he was unaware that he was BC.) I guess it worked. We are still today reading about Gaius Cestius, an otherwise unremarkable Roman official who died more than 2000 years ago. I guess the guy had some class. A pyramid is a good structure for the ages. It is an easy form to build and it is very stable.
My other pictures are fragments of the old Roman wall. There was no wall when Cestius built his tomb. They built the wall around it later.
