Castel Sant'Angelo. Also known as Hadrian's Mausoleum, Castel Sant'Angelo is a circular fort and castle complex that was once the tallest building in Rome. Built in 129 AD, the castle is truly ancient and was originally intended to serve as a mausoleum for the emperor. With the passage of time, the castle became part of the Vatican State and was connected to St. Peter's Basilica through a huge corridor called Passetto di Borgo. Today, the castle is a museum and contains wonderful exhibits about the history of the structure throughout history. It is also possible to climb to the top of the castle walls to admire the fantastic views of St. Peter's Square and the city of Rome.
