About Castel Sant Angelo
Castel Sant Angelo in Rome was originally constructed as the magnificent Mausoleum of Hadrian, the fourteenth emperor of Rome from 117AD to 138AD. It is unclearly as to exactly when Castel Sant Angelo was built, but most sources date it to between 123 and 139 AD.
A fortress-like structure, successive Roman emperors and other leaders used Castel Sant Angelo for a variety of purposes. In 401, Emperor Flavius Augustus Honorius incorporated Castel Sant Angelo in Rome’s Aurelian Walls, destroying and losing many of the contents of Hadrian’s mausoleum in the process. It later turned into a medieval stronghold and a prison.
In the fourteenth century, popes began using Castel Sant Angelo as a place of safety, an emergency shelter in times of danger. In fact, there is a corridor linking Castel Sant Angelo with Vatican Palace. Various changes were made to Castel Sant Angelo in order to meet the requirements of the popes and to further fortify this already well-defended building.
Today, Castel Sant Angelo houses a museum which tells the story of its history, from the Roman remains of the Mausoleum of Hadrian to remnants of the fortified castle, the original prison cells and the papal apartments.
