Rome is a beautiful city, filled with history, vibrant night life and lots of social friendly people.
In the 4 days we spent in Rome we went to see Colosseum.
The Colosseum stands on 2 ha of property. Also known as the Flavian Amphitheatre. Construction started in 72 and was completed in 80 AD.
One gets a 2 day pass to vist the Colosseum and grounds. You will most definitely need this time to appreciate everything you need to see.
