Mausoleum of Augustus was built on the Martian Field, Rome, in 29 BCE by Octavian Augustus as a burial place for myself and my family. It is a building located on the top of an artificial mound, set on a high podium. It may not have a structure as complicated as the Egyptian pyramids, but you could still get lost inside.
It has the shape of a circle with a diameter of 87 meters. The podium structure consists of five vertebrae centrally located around a pole over 44 meters high, which was probably crowned with a bronze statue of the founder, Octavian Augustus. The passage ( dromos) led to the corridor between the third and second (from the inside) ring. The corridor led to the burial chambers. The place for August’s ashes was prepared in the center, inside the pillar. Family members, incl. Octavia, Agrippa, Germanicus, Livia, Tiberius, Caligula and Claudius were buried in the burial chamber between the smallest podium ring and the pillar.
Of course, no imperial remains have survived to this day. The ashes were put in beautifully decorated urns, made of gold or other precious metal, which was an interesting loot for everyone. It is suspected that the urns were probably stolen either by the Visigoths (410 CE) or the Vandals (455 CE) during the capture of Rome or in later times, when the building fell into ruin. The ashes, in turn, were probably simply poured.
The entrance to the Augustus mausoleum was located on the south side. Two Egyptian obelisks stood in front of the entrance, on the sides. The mound itself was covered with earth and topped with a bronze monument to the emperor.
