The historic EVR district is the jewel in the crown of 20th-century Italian rationalist architecture. A cultural hub for the capital in terms of major international events and exhibitions, the EVR is home to some of Rome's most prestigious buildings. Among these, the Nuvola, a famous project by architect Massimiliano Fuksas, and the Palazzo dei Congressi, both managed by Roma Convention Group.

The architectural complex of the Cloud is divided into three elements: the case, the Cloud and the hotel. The Cloud, with its extraordinary visual effect, floats in a steel and glass case that is 40 meters high, 70 meters wide and 175 meters long. The entire complex was designed to be highly flexible and able to adapt to events of different nature and size, thanks also to an overall capacity of approximately 8,000 seats. The structure includes a 4-star hotel designed to facilitate the logistics relating to events and conferences.

The Palazzo dei Congressi , built for the Universal Exhibition of Rome in 1942, has been the stage for some of the most important sporting and international events over the years thanks to the extraordinary capacity and free volumes of its structure.
