I found this composition while walking the ramparts and courtyards of the Castel Sant’Angelo, which is a very easy place to get lost in if you’re not paying attention. There are so many levels and layers, both physically and historically. The building was built originally as the funerary monument for the Roman emperor Hadrian. Later it was converted into a fortress for the protection and safety of the Pope. A residential suite complete with reception rooms and treasury (three massive barred iron chests with multiple locks, each of which only one person had the key to, so it would require all the key holders to open each chest) and balconies with sweeping panoramic views of the city were put on the upper tier, and the burial chamber of the emperor Hadrian was converted into a dungeon where prisoners could be thrown to wither and die in darkness and misery.
