Castel Sant'Angelo has an atypical destiny in the historical-artistic panorama of the capital. While all the other Roman monuments are overwhelmed, reduced to ruins or quarries of bare materials to be recycled into new, modern buildings, the Castle - through an unbroken series of developments and transformations that seem to slip into one another without solution of continuity - accompanies the destiny and history of Rome for almost two thousand years. From a funerary monument to a fortified outpost, from a dark and terrible prison to a splendid Renaissance residence that sees Michelangelo active from within its walls, from a Risorgimento prison to a museum, Castel Sant'Angelo embodies the solemn Roman spaces, the mighty walls, the magnificent frescoed rooms the events of the Eternal City where past and present seem to be inextricably linked.
