Juxtaposition

You wouldn't think that Rome needed another museum full of ancient white marble things. But you probably haven't seen the Centrale Montemartini, a decommissioned power plant on the southern edge of town. It became a permanent gallery in 2005 after hosting a wildly successful temporary exhibition in the late 90's. Two enormous black turbines fill the main room, looming over a tasteful collection of marble sculptures and artifacts from many moons ago. A few photos here.

The museum is far enough from the beaten path that it attracts an average of only 50 visitors/day, but you can reach it easily enough on the Metro (Linea B to Garbatella).
