The Octagon House
A preeminent example of Federalist architecture, the Octagon House was designed by Dr. William Thornton, first architect of the U.S. Capitol, and built for Colonel John Tayloe, one of the richest plantation owners in Virginia. Completed in 1800, Colonel Tayloe provided his house for use as President Madison's temporary executive residence after the British burned Washington. The Treaty of Ghent, ending the war of 1812, was signed in the room above the rounded entrance pavilion.
In 1899 the Octagon House became home to the American Institute of Architects. Today, AIA retains ownership while residing in the building located directly behind the house, choosing to open this National Historic Landmark to the public as a museum. The Octagon is open from 1-4pm on Thursday through Saturday.
