Castel Sant'Angelo: A Destination, Its History, and First Impressions

The Mausoleum's Origins and Tiber Location

Castel Sant'Angelo began as the Mausoleum of Hadrian, constructed between 123 and 139 AD on the right bank of the Tiber River in central Rome. This massive cylindrical tomb was designed to house the remains of Emperor Hadrian and his family, mirroring earlier imperial mausoleums like Augustus'. Positioned strategically near the Vatican, it fits perfectly into Rome's historic core, linking ancient imperial power to later Christian history.
