La Nuvola (Roma Convention Center)

Massimiliano Fuksas's convention centre, in three parts: la teca, a glass case 40 m high, 70 m wide and 175 m long, built with 18,000 tonnes of steel, 42,000 glass panels, 25,000 m2 of travertine and 28 lifts; la nuvola, a curved steel skeleton clad in perforated siliconed glass fibre holding an auditorium of 1,748 seats; and la lama, the tower occupied by the Hilton Rome EUR La Lama. There are over 26,000 m2 of usable space. It is a working convention centre, and no source states its opening hours, so none are given here.
