Fodor's Expert Review Boréalis

Back when Trois-Rivieres was a lumber, paper, and pulp industry leader, this plant’s machinery whizzed and whirled. Built in the early 1920s, it pumped, filtered, and stored water for the paper mill. By the mid-1950s, the plant filtered more than 20 million gallons of water a day that was used to produce 1,000 tons of newsprint. Today, it is eerily quiet, especially the long-abandoned underground vaults, which are part of the original architecture and machinery that's on display.
