The Colosseum is listed as one of the New7Wonders of the World.
There are two facts impressed me mostly after visiting this tourist object.
This huge and complicated engineering construction has been built just in seven years. The Colosseum is an immense work of engineering, and needed professional, skilled workers. Slaves would only have been used in the quarries to quarry the stone needed.
Nowadays we can see just skeleton of that beautiful masterpiece. It happened not just because of time and nature disasters but people. All the numerous statues and marble tiles from exterior and interior decor have been robbed by Romans to build their own palaces. Even Vatican took place in that robbery.
Only one’s imagination can draw the real view of this Architectural, Engineering and Art Masterpiece.
