The Blackstone River Valley National Heritage Corridor is a region of nearly 400,000 acres located within Worcester County in central Massachusetts and Providence County in northern Rhode Island. It includes cities, towns, villages and almost one million people. The American Industrial Revolution began in the Blackstone River Valley. It changed the landscape of the Valley and transformed life in America. The Blackstone River provided the waterpower for the birth of industry in America with its 438-foot drop over a 46-mile length. Even today, the Valley retains its “wholeness” as a unique landscape with a concentration of historic, cultural and natural resources that represent 18th and 19th century industrial production in America.
