The Harvey-Niemeyer House is an example of Early Transitional architecture that combined Sonoran and Victorian elements. Built of adobe in 1880, the house was later veneered with red brick to give it a Victorian appearance. Physician William Harvey was known as an "Angel of Mercy" during a smallpox epidemic and was on scene at the aftermath of the 1888 Gabriel-Phy shootout. Later resident Charles Niemeyer was Clerk of the Pinal County Board of Supervisors for 25 years and also served as local postmaster. It is listed on the National Register of Historic Places.
