Outside the Vatican I feel relieved. Now I can think again about women and don't have the sensation I will spend my next life in hell!
On the left you see the 'Castel Sant'Angelo', constructed to hold the grave of the emperor Adrian. It is supposed to be one of Rome's landmarks, but from here it's not such an impressive building. The Castle has a long and interesting history, though. It was a fortress, and during the Renaissance, a jail. Nowadays you will find a huge collection of military objects, and several rooms decorated with frieze --many of them works of Perin del Vaga--, and several Renaissance’s canvases and furniture.
If you visit the Castle, you should not miss the San Clemente VII rooms with pictures by Crivelli and Signorelli. In the third floor you will find the Pope rooms with several works of art and the Adrian Mausoleum.
