Built in 1803-1804, the Abbot-Spalding House exemplifies Federal and Colonial Revival architecture in Nashua, with an interior featuring fine woodwork and cabinetry. Daniel Abbot, known as the "Father of Nashua," and his family were the original residents. William Spalding, a noted banker and antique dealer, and his family were the last residents. Spalding and his cabinetmaker son, Dexter, updated the residence with Colonial Revival detailing in the early 20th century. The house was acquired by the Nashua Historical Society in 1978.
