The history of the new exhibition space for the Musei Capitolini in the former Giovanni Montemartini Thermoelectric Centre, an extraordinary example of industrial archaeology converted into a museum, began in 1997 with the transfer of hundreds of sculptures to the new location during the restructuring works carried out across much of the Capitoline complex.

To create space in the Museum of the Palazzo dei Conservatori, the Museo Nuovo and the Braccio Nuovo, while keeping the works of art accessible to the public, an exhibition was created in 1997 in the restructured rooms of the first public electricity plant in Rome. The exhibition was entitled “The machines and the gods”: it put side by side two diametrically opposed worlds, those of classical art and industrial archaeology.
In an atmospheric game of contrasts, the old machinery of electricity production became the backdrop for masterpieces of ancient sculpture and precious goods found in the excavations of the late nineteenth century and the 1930s. The display reconstructs some of the great monumental complexes and illustrates the development of the ancient city from the Republican era to the late imperial age.
The adaption of the building into a museum, the restoration of the machines and the educational sections about industrial archaeology have all been created by ACEA.

The outstanding museum space was originally thought of as a temporary solution. However when part of the sculptural collection was returned to the Campidoglio in 2005, on the conclusion of the restructuring works, it was decided to turn the building into a permanent location for a collection of the Museio Capitolini’s most recent acquisitions.
The space is used for continual experiments in possible display methods, particularly those connected to scientific research on the remains; bringing together works from the same area of provenance also allows the links between the museum and the fabric of the ancient city to be continually renewed.

The museum itself is part of a wider project to redefine the Ostiense Marconi area, converting it into a cultural centre for the oldest industrial area of Rome (including, as well as the electricity plant, the Slaughter House, the Gasometer, structures from the docks, the old Mira Lanza site and the old General Markets), with the defining structure of the university campus of Roma Tre and the creation of the City of Science.
