Rome

The Colosseum is an ancient Roman amphitheater built between 70–80 AD, capable of seating 50,000 to 80,000 spectators. It was used for gladiatorial contests, public spectacles, and animal hunts. Today it stands as the most iconic symbol of the Roman Empire and one of the greatest architectural achievements in history.

The Vatican Museums are a vast complex of art and history amassed by the Roman Catholic Church over centuries, housing over 70,000 works and displaying 20,000 of them. They include the Sistine Chapel with Michelangelo's famous ceiling frescoes, and the Raphael Rooms with masterful Renaissance paintings.
