Johnston–Felton–Hay House

The Johnston–Felton–Hay House, often abbreviated Hay House, is a historic residence at 934 Georgia Avenue in Macon, Georgia. Built between 1855 and 1859 by William Butler Johnston and his wife Anne Tracy Johnston in the Italian Renaissance Revival style, the house has been called the "Palace of the South." The mansion sits atop Coleman Hill on Georgia Avenue in downtown Macon, near the Walter F. George School of Law, part of Mercer University. It was designated a National Historic Landmark in 1973 for its architectural uniqueness.

The 18,000-square-foot (1,700 m²), 24-room home was designed by the New York architect T. Thomas and Son. It was built in part by craftsman and artisans brought from Italy who were supervised by local master builder James B. Ayers. It has four levels and is crowned by a three-story cupola. Commissioned by imaginative owners and constructed by the most skillful workers of the time, its technological amenities were unsurpassed in the mid-nineteenth century: hot and cold running water, central heat, a speaker-tube system connecting 15 rooms, a French lift equivalent to today's elevator, in-house kitchen, and an elaborate ventilation system.
