Centrale Montemartini

The extraordinary Centrale Montemartini is an outpost of the Capitoline Museums housed in a former power station (closed in 1930) in Southern Rome. Originally a temporary arrangement while the Museums were being reorganised, the juxtaposition of statues and machinery proved so popular that it became permanent.
