Rome is full of beautiful museums and archaeological sites, so that often, if you spend only a few days in the capital, you are forced to select one to visit. Besides the most famous Vatican Museums and Galleria Borghese, there is a probably lesser-known gem that is absolutely worth a visit: the Centrale Montemartini. 

Located in the Ostiense district, originally an industrial area of the capital, this museum offers a collection of about 400 Roman sculptures, mosaics and epigraphs, in the extraordinary setting of an old thermoelectric factory, now considered an amazing example of industrial archaeology. Opened in 1912, this factory became the first public electricity plant, assuming the name of the councilor and municipalization theorist who supported its construction, Giovanni Montemartini.
