Centrale Montemartini

"Centrale Montemartini Museum Centrale Montemartini, the sister space to Rome ’s historic Capitoline Museums, is located in the Ostiense neighborhood. The museum is housed in the city’s former thermoelectric center—a turn-of-the-century power plant still outfitted with original turbine engines, boilers, and compressed air canisters—creating an unusual backdrop to an incredible collection of antiquities. Ancient Greek and Roman sculptures, friezes, and mosaics. The less-visited museum is one of the best places for full immersion in Roman history and antiquities."

"Inside a former power plant in up-and-coming Ostiense, a few metro stops south of the Colosseum, this small museum houses ancient Roman sculptures. Much of its collection is spillover from the Capitoline Museums while its floors feature large mosaics of hunting scenes and are instagrammable in themselves. Bonus: it's location means you will often get the industrial space all to yourself." - Laura Itzkowitz
