Completed in 1822, Dormitory No. 2 at 402 Main St. was one of the major communal buildings of the Harmonie Society and housed forty to sixty people. It is a full story taller than other Harmonist dormitories. Constructed of heavy timber framing, as were all Harmnist buildings, it was nogged with lightly baked porous brick to serve as insulation and firewall. The outer face was bricker and the inner ploastered and painted. Dutch biscuits, mud-plastered straw-wrapped boards, were used between floors for insulation. The building has sixteen fireplaces, fifteen of which were used for heating and one for winter cooking.... After 1825, during the Owen/Maclure period, Dormitory No. 2 was used as a school, functioning as the center for William Maclure's educational experiments with Pestalozzian teaching. Between 1831 and 1940 the building housed a variety of businesses including a hotel, tavern, print shop, cigar factory, and hardware store. (Walker, Janet R. Walker's Guide to New Harmony's History.
