Blackstone River Valley National Historical Park Blackstone River Valley National Historical Park is a National Park Service unit in the states of Rhode Island and Massachusetts. The park was created for the purpose of preserving, protecting, and interpreting the industrial heritage of the Blackstone River Valley and the urban, rural, and agricultural landscape of that region. The Blackstone River Valley was the site of some of the earliest successful textile mills in the United States, and these mills contributed significantly to the earliest American Industrial Revolution. The subsequent construction of the Blackstone Canal, a few years after the successful completion of the Erie Canal, helped to sustain the region's industrial strength.
