The Pyramid of Cestius is an ancient pyramid near the Porta San Paolo and was built around 15 BC as a tomb for Gaius Cestius Epulo. It measures 27 meters in height and 22 meters in length at its base. The shape of the pyramid has close resemblance to the pyramids of Nubia, especially of the kingdom of Meroë, which was attacked by Rome in 23 BC. It might be so that Cestius was involved in these attacks and wanted the pyramid to serve as a commemoration.
