Visit the historic remains of the Tremont and Suffolk Mills, examples of 19th century waterpower systems. The Tremont Mills and the Suffolk Manufacturing Company were each incorporated in 1831 and were later merged into one company in 1871.  The technology which powered the Tremont Mills remains visible in the basement of an office building, while the Tremont mill yard retains remnants of mill features and waterpower systems. The tour concludes at the Suffolk Mill, where turbines from 1896 are still in place.
