Two mills survive from the Whitin Machine Works (originally Paul Whitin and Sons). The Whitin company was founded with the construction of the brick mill in 1826 and survived as a textile producing company until its closure in 1966. They also built a second stone mill called the Whitinsville Cotton Mill (or "The Shop" to locals) in 1845 which later became a facility for designing and testing new textile equipment.
