“La Nuvola” or “The Cloud” is the new Convention Center, designed by Alessandro Fuksas, under construction in EUR district in the city of Rome. You will find some infos about “The Cloud” in this page. Please note that the page was published on november 11th 2004. The page states that: “will be open to the public by 2007“.
I didn’t even remember that deadline… I had considered a second deadline for 2010 more reliable.
Foksas himself fears the closing of the construction for 2017 or 2018 in an interview published by La Repubblica.
