My italian adventures

What’s up?
Good afternoon
Today, I am going to tell you about my trip to Italy in 2013.
I visited the cities of Florence, Venice and Rome. It was amazing, but a little tiring ! I walked a lot.
I had the opportunity to visit the Coliseum which is a reference of today's Roman architecture. (do you mean to say 'which is a monument of Roman architecture? I thought the Coliseum is really old, but your sentence implies it is 'today's architecture')
The Coliseum is huge and wonderful. It's main intention was the fun of the people. That is, a place built for the public spectacles and for the fights of the Roman gladiators. The emperor Vespasian had taken over when the Coliseum was built. Its construction was with concrete, sand and stone, but the arena was made of wood. It is 45 meters high and is the largest amphitheater in the world and one of the greatest symbols of the Italian city. The places were divided according to the social classes of the time. In Ancient Rome, it housed between 50 and 80 thousand people. It had about 80 stairs, which facilitated the exit of so many people. Some shows included exotic animals such as lions, panthers, elephants, rhinos and giraffes.
As it is a very old place, it always needs repairs. Like this The Coliseum had begun his repair works when I arrived.
The weather did not help much, it was rainy but even so I enjoyed it a lot.
See you later.
