Far less crowded than the central museums — almost always near-empty.
Via Ostiense, 106, 00154 Roma RM, Italy
An extension of the Capitoline Museums, brilliantly housed inside Rome's first municipal power plant (1912) — ancient Roman marble gods and emperors stand beside vast diesel engines, turbines, and steam boilers. The juxtaposition is unforgettable. A short tram ride from the centre, in the Ostiense district near the Pyramid of Cestius.
