About Blackstone River Valley National Historical Park
The Blackstone River powered America's entry into the Age of Industry. The success of Samuel Slater's cotton spinning mill in Pawtucket, RI touched off a chain reaction that changed how people worked and where they lived. Learn how this revolution transformed the landscape of the Blackstone Valley and the United States. The Visitor Center at Old Slater Mill is closed for the winter season.
