One of Rome’s most important modernist buildings, it was built in 1978 to house the ExxonMobil/Esso headquarters in Italy. It is a masterpiece by architect Julio La Fuente in collaboration with the engineers Gaetano Rebecchini and Calogero Benedetti.

The prestigious building complex is known for the architectural peculiarity of the three fans that give it shape. Given the nature of the foundations, located just a few metres away from the bank of the Tiber river, these respond to the structural need of reducing the number of supporting sections to the entire building.

The building, which distinguishes the skyline of the Rome-Fiumicino motorway, comprises three eight-floors above ground sections, for office use, (named towers A1-A2-A3) and a longitudinal two-floors above ground section (named section B) mainly used as a company cafeteria and restaurant. The underground floor houses the car parks. The load-bearing structure is made of iron and reinforced concrete and the façade of glass and burnished aluminium. The property is complemented by a vast green area and a parking area.
