The Centrale Montemartini is an archaeological museum on Via Ostiense in Rome. It is part of the Capitoline Museums and occupies a former thermoelectric power station that was originally built to produce electricity for the city.
The museum is known for an unusual combination: ancient Roman sculptures, mosaics, and archaeological finds are displayed among the preserved engines, turbines, boilers, and other machinery of the former power plant. The result brings together two very different periods in Rome’s history—Ancient Rome and the city’s industrial development in the 20th century.
From Power Station to Museum
The Centrale Montemartini opened in 1912 as Rome’s first public electricity-generating plant. It was built during the administration of Mayor Ernesto Nathan as part of the city’s development of municipally operated public services.
In 1913, the power station was named after Giovanni Montemartini, an economist and member of Nathan’s administration who had been closely involved in Rome’s municipalization of public services.
Via Ostiense was a practical location for the new power station. The site was close to the Tiber, providing the water required for its machinery, and had good road and railway connections. The surrounding area was becoming an important center for Rome’s modern infrastructure and industrial development.
The power station eventually became obsolete and ceased producing electricity in the 1960s. The historic industrial complex was later restored by Acea, with some of its original machinery preserved.
The Birth of the Museum
The transformation into an archaeological museum began in 1997.
At the time, parts of the Capitoline Museums were undergoing major renovations. Rather than removing important works from public view, a selection of sculptures and archaeological finds was transferred to the former power station.
The temporary exhibition was called The Machines and the Gods. Ancient sculptures were placed alongside the enormous industrial machinery that remained inside the building.
What began as a temporary solution became one of the defining characteristics of the museum. The exhibition attracted considerable interest, and Centrale Montemartini became a permanent museum in 2001.
The Archaeological Collection
The museum displays sculptures, mosaics, architectural decorations, and other archaeological material belonging to the collections of the Capitoline Museums.
The collection includes works from different contexts in ancient Rome, including temples and public buildings as well as private residences and gardens. Some of the material was discovered during the extensive construction and urban transformation of Rome in the late 19th and early 20th centuries.
The museum’s presentation also preserves the industrial character of the building. Roman marble sculptures appear against diesel engines, turbines, pipes, and other machinery from the former power station.
The machinery is therefore more than a backdrop for the archaeological collection. It represents another period in the history of Rome.
Two Different Romes in One Place
Centrale Montemartini brings together two periods that visitors to Rome do not normally encounter in the same place.
The archaeological collection represents the ancient city: its temples, public spaces, houses, gardens, religious practices, and artistic culture.
The building represents another Rome—the city that expanded and modernized after becoming the capital of unified Italy.
This second story is closely connected with Ostiense. During the late 19th and early 20th centuries, the area developed as an important zone for industry, transportation, energy production, and other infrastructure needed by the growing capital.
Centrale Montemartini physically connects these two histories.
Ancient sculpture and modern machinery occupy the same rooms, making the museum an unusual example of how different layers of Rome’s history can survive together rather than simply replacing one another.
