Built by Emperor Adriano in the 2nd century AD, Castel Sant’Angelo was originally built as a mausoleum for himself and his family. The castle is now a prominent landmark in Rome and one of the most visited attractions in the city.
The castle is built in a unique zig-zag shape, with a large courtyard and an impressive inner courtyard. The building is also home to several interesting artworks and sculptures and is the site of the famous Angel Bridge, which is one of the most iconic bridges in Rome.
