Longwood

Longwood is a historic mansion located in Natchez. It is the largest octagonal house in the United States, listed on the U.S. National Register of Historic Places and designated as a National Historic Landmark. The home was designed in the Oriental Villa style, with a unique onion-shaped dome on the highest of its six floors. Construction began in 1860 and was halted a year later due to the outbreak of the Civil War, leaving only nine rooms of the home’s basement level finished. The home, which is one of Natchez’s most visited attractions, is open for tours year-round.
