Built about 1861, this house was reportedly the site of the signing in September 1872 of the final peace treaty ending the Black Hawk War between Mormon settlers and Indians in the area. William S. Seeley, who lived here until his death in 1895, was prominent in the establishment and later growth of the City of Mt. Pleasant, serving for nearly thirty years as the LDS Bishop in the community and also as mayor for a total of seven years. Reportedly the first house built outside the walls of the pioneer fort, it is also a well-preserved example of the central passage plan, a house type common in Utah from 1847 to 1900 but relatively rare in Mt. Pleasant. Rear additions were built about 1880 and about 1910, and despite its stucco covering, common on many adobe buildings, it remains one of the oldest and best preserved pioneer-era structures in Mt. Pleasant.
