While the interior is badly preserved the exterior has survived relatively well thanks to the incorporation of the pyramid into the Aurelian wall in 275 BC. Its marble casing was restored in the XIIth century. Only three Egyptian pyramids - the main pyramids of Gizeh - are taller than this Roman imitation. It tells us something about the wealth of Rome during the reign of emperor Augustus, when a single citizen - albeit a rich one - was able to build a pyramid worthy of Pharaohs. In addition to obelisks and other Egyptian imports there was actually another, larger pyramid in Rome, known as the "Pyramid of Romulus" near the Castel Sant'Angelo. This pyramid did not survive the building crazes of later generations, and its marble was used in the building of the stairs at St. Peter's Basilica.
Cestius pyramid is located jsut next to metro station Pyramid.
