Mausoleum of Hadrian (Castel Sant'Angelo) - Roma, Italy

WikiPage

 The Mausoleum of Hadrian, usually known as the Castel Sant'Angelo, is a towering cylindrical building in Rome. It was initially commissioned by the Roman Emperor Hadrian as a mausoleum for himself and his family. The building was later used by the popes as a fortress and castle, and is now a museum.

The tomb of the Roman emperor Hadrian was erected on the right bank of the Tiber, between 135 and 139. Originally the mausoleum was a decorated cylinder, with a garden top and golden quadriga. Hadrian’s ashes were placed here a year after his death in 138, together with those of his wife Sabina, and his first adopted son, Lucius Aelius, who also died in 138. Following this, the remains of succeeding emperors were also placed here, the last recorded deposition being Caracalla in 217.
