The Colosseum is a monument of epic proportions dating from AD 72. Stories of gory battles between gladiators, slaves, prisoners and wild animals have emerged from this Flavian amphitheatre with a seating capacity of over 50,000 people; nowhere in the world was there a larger or more glorious setting for mass slaughter. This is a necessary pilgrimage for history buffs and the ideal starting point to take in the Roman remains of the city: the jaw-dropping Forum, the Domus Aurea and the Pantheon.
Where? Piazza del Colosseo.
Time Out tip: The best time to visit the Colosseum is early in the morning, or if you prefer, in the late afternoon before closing to avoid the sun.
