Torri ENEL, Modern office building in Centro Direzionale, Naples, Italy

Torri ENEL are two identical 122-metre office towers in lots 1 and 3 of islands A and G in Naples' Centro Direzionale, designed by Giulio De Luca, Renato Avolio De Martino with his son Francesco, and Massimo Pica Ciamarra. Each has around thirty floors, with offices hung by steel cables from a central steel beam set across two reinforced-concrete cores that hold the stairs, lift doors and corridor entrances. The two are mirrored across the central avenue's axis and tilted about 45 degrees.

The two towers were erected between 1985 and 1990 to a design by Giulio De Luca, Renato Avolio De Martino with his son Francesco, and Massimo Pica Ciamarra. They form lots 1 and 3 of islands A and G in the Centro Direzionale, the business district built east of the historic centre. Both were later sold by ENEL; tower A1 stands empty awaiting renovation for BD Tower offices, while tower G3 partly houses SORESA offices.

Locals call the pair the Twin Towers of Naples because the two buildings are identical and set mirror-like on either side of the central boulevard, each rotated about 45 degrees. The name ENEL comes from the national electricity company that commissioned them and later sold both towers; tower G3 now houses offices of SORESA.

The buildings are most easily reached via the Centro Direzionale metro station, which connects directly to the towers. The complex has modern elevator systems and clear signage for visitors.

A team of five architects, including Massimo Pica Ciamarra and the De Martino brothers, collaborated on the structural engineering of these towers. This collaboration was notable for a project of this scale and complexity.
