Metropolitan Waterworks Museum - 2450 Beacon Street, Boston, Massachusetts, USA

The Metropolitan Waterworks are located at the Chestnut Hill Reservoir in Boston. Unlike other examples above, this was the real deal. The waterworks were built in 1887 to supply water to the city until the Quabbin Reservoir became the main water source in the 1970s. The site was fallen into ruins until Friends of the Waterworks advocated for the preservation of the building and its equipment in 1991. In 2005, legislation was passed to redevelop the site as a museum.
