After discovering the history of the bridge with your private guide you will enter to Castel Sant'Angelo and to admire the historical development of this important place which has been first a Roman tomb, then a papal residence, fortress, prison, and execution ground, and currently a museum offering one of the most amazing views over the city of Rome. You’ll visit several rooms used by the popes. But beyond the amazing decorations, golden stuccos, sparkling marble floors, the castle hides a dark heart: the dreadful prisons, the most terrible one was inserted in a vent over the helicoidal ramp of Hadrian’s Mausoleum, a small room accessible just from a trapdoor, and another one in the floor was used to get rid of corpses. The Castel has also inspired several writers and directors, for example, Dan Brown in his best seller “Angels and Demons” You’ll climb to the top of the building to the terrace, where you’ll enjoy stunning views of the Rome and a great place for selfies.
