The Eli Morse Sawmill Foundations are the surviving remnant of the first industrial site in Dublin, New Hampshire. The site is located astride a stream, near an old logging road, south of Old Marlborough Road, not farm from the Eli Morse Farm. It consists of four foundation walls made of dry laid granite boulders. The northern wall measures about 10 feet (3.0 m), and the others measure about 23 feet (7.0 m). To the west of the main mill's foundations are smaller foundations of extensions or outbuildings. The mill site was listed on the National Register of Historic Places in 1983.
