The Castel Sant'Angelo Monument, or Hadrian's Mausoleum, is located on the right bank of the Tiber, in front of the Sant'Angelo Bridge and not far from the Vatican.

Castel Sant'Angelo has had an atypical destiny in the historical-artistic panorama of Rome. Built around 123 AD as a tomb for the emperor Hadrian and his family, while all the other monuments of the Roman era were overwhelmed, reduced to ruins or quarries of spoiled materials to be recycled in new, modern buildings, Castel Sant'Angelo - through an uninterrupted series of developments and transformations that seem to slide into one another without interruption - accompanies the fate 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 within its walls, from a Risorgimento prison to a museum, Castel Sant'Angelo embodies in the solemn Roman spaces, in the mighty walls, in the sumptuous frescoed rooms, the events of the Eternal City where past and present appear inextricably linked.

Since its establishment in 1925, Castel Sant'Angelo has undergone numerous transformations and interventions, establishing itself in the Capitoline cultural reality as an active hub, capable of catalyzing the interest of the millions of visitors who flock to its spaces every year to visit its suggestive rooms, admire the precious collections of paintings and artefacts, enjoy the numerous exhibitions and temporary exhibitions that take place inside the Castle throughout the year.
