Before the invention of plastic, ivory was an important material used in the manufacture of many different products. As ivory became more expensive and plastic more widely used, Deep River lost one of its major industries. However, the industry has left an indelable mark on the town. The Piano Works building is now an apartment complex but in the early half of the century it produced many fine ivory products. The buildings other claim to fame was that in the second world war it produced gliders for the army to ferry men and material into combat.
Deep River has a great public library that has recently been modernized and extended.
The mix of shops and businesses are not as tourist oriented as Chester but are much more practical for day to day living. Deep River has its share of antique shops as well as the best shopping center for every day needs. There is also live music in the summer evenings. When it does it bustles with people taking advantage of the amenities the town has to offer. The Deep River Historical Society runs the Stone House which is open on Saturday and Sunday in July and August.
