One of the “musts” during a stay in Rome is a visit of the central archaeological area of the city including the Colosseum, the largest amphitheatre ever built by the Ancient Romans, the Roman Forum, the main square of the ancient city and the heart of the public life, as well as the Palatine Hill, on which, according to the tradition, Rome was founded in 753 BC by Romulus and later the emperors built their splendid residence.
