The former Sheffield Mill is historically and architecturally significant as one of the last remaining large-scale manufacturing complex to survive in the village of Saugerties, New York. The building was constructed in 1887 as the J. B. Sheffield Paper Company and was used for the manufacturing of envelopes and bank bookbinding. In the 1930s, the building was purchased by the Knaust Brothers, who grew and harvested mushrooms in nearby towns, making mushroom beds or trays in this building. The Knaust Brothers were at one time, one of the largest firms growing and canning mushrooms in the world. The former mill was vacant by the late 20th century and its future was uncertain until it was renovated at the turn of the present century into senior housing. What a great rebirth of a great old mill!
