Well obviously as you probably know the Eiffel Tower is one of the biggest attractions in Paris, so it would be unjust not to mention it here. The best part of seeing was watching the masses of people that were always around it. It was amazing to see that many tourists in one place. It's amazing and exciting at the same time being very peaceful.
The Colosseum: No visit to Rome is complete without having seen its magnificent Colosseum, a vast amphitheatre with seating for 55,000 that was designed as a horse racing circuit and arena for animal fighting and gladiatorial battles.
