Calatrava City of Sport
The innovative City of Sport project, designed by the internationally renowned Spanish architect Santiago Calatrava was an integral part of the city of Rome's bid for the 2020 Summer Olympics and would have hosted the volleyball, gymnastics, trampoline, and basketball finals.
This building is well known from Romans because is clearly visible
from the main highway that connects the city but no one entered inside
The two main buildings of the project the Sport Forum and Swimming Forum are symmetrical; each of them is about 21,600-square-metre (5-acre) in area and about 75 m in height.
The complex, whose construction began in April 2007, was to be completed in 2009 in time for the 2009 World Aquatics Championships but is still under construction.
