The technical drawings stored in Eni's Historical Archive bear witness to the vast dimensions of the property portfolio of Eni and its companies: from office buildings to service stations and from motels to buildings devoted to company welfare, such as homes for employees, churches, sports facilities and holiday camps. Some of them also illustrate more strictly technical subjects such as oil pipelines, natural gas pipelines and ships in the company fleet. The creators of these works are mostly internal designers in the technical sections of the companies (Agip, Snam etc.), but there are also plenty of "big names" like Mario Bacciocchi, Marcello Nizzoli, Mario Ridolfi, Marco Bacigalupo and Ugo Ratti.
