Favorite thing: We must visit Colosseo which took about 8 years to build. It mainly for the entertainment to the king of Roman empire. Many Gladiator and animal had been killed in a fight.
Favorite thing: Also near the Colosseum is the Arch of Constantine. He was the first Roman Emperor to embrace Christianity.
Favorite thing: The Colosseum is, of course, the symbol of Rome. It is also the favorite home of stray cats. I don't know why they hang around there. They just do.
Favorite thing: See the Colosseo. It was commissioned by Emperor Vespasian in 72 AD. Deadly gladiatoral combats and wild animal fights took place here.
Favorite thing: THE COLOSSEUM (or 'Flavian Amphitheatre'), completed in 81 AD. No further commentary is required, I think -- the place speaks for itself!
Favorite thing: visit the Colosseum and the Vatican City. It'll most probably take you more than half a day to cover these 2 places and to fully absorb the culture and ambience of the 'Roman era'.
Favorite thing: Rome = Colloseum !!! Do discussion. This is a must to see when visiting Rome. There you will also find Romans dressed like the used to in 'those glory days'.
