Octagon House is a valuable mansion located in the Foggy Bottom neighborhood of Washington, D.C., United States. It was built in 1799 and is one of only three remaining historic houses that have served as presidential residences, along with the White House and Blair House, making it one of the five residences used by presidents in American history.
Octagon, but it’s actually a hexagon? The origin of the building
The Octagon House in Washington, D.C., is indeed shaped like a hexagon, despite its name. This building was designed by American architect William Thornton in the late 18th century and was originally used as the headquarters of the U.S. Navy.
The name “Octagon House” is derived from the octagonal room located in the center of the building. However, the overall shape of the building is hexagonal, causing a discrepancy between the name and its actual form.
John Tayloe III and the history of Octagon House
Octagon House was constructed by John Tayloe III after he inherited Mount Airy, a colonial-era mansion on the northern bank of the Rappahannock River in Richmond County, Virginia, which was built by his father, John Tayloe II. He was educated at Eton College and Cambridge University and served in the Virginia State Legislature before running for the U.S. House of Representatives in 1800.
Octagon House as a presidential residence
During the War of 1812, the White House was destroyed, and Octagon House served as the residence for President James Madison and First Lady Dolley Madison for six months. Subsequently, Octagon House changed hands multiple times and is now used as a museum.
Current status of Octagon House
Currently, Octagon House is open to the public as a museum, and visitors can pay an admission fee to explore the interior. It is open only during the summer season, and being one of the few remaining historic mansions in the city, it attracts many tourists.
