Washington - Octagon Museum

Near the White House stands the Octagon, one of the first great homes built in the new nation's capital. The Octagon is a noted landmark of America's architectural, political, and cultural history. Completed in 1801 for the eminent Tayloe family and designed by William Thornton, the original architect of the U.S. Capitol, the home is one of the most significant buildings to remain standing from the early federal city.

It was in the upstairs parlor that President Madison signed the Treaty of Ghent on February 17, 1815 establishing peace with Great Britain. In 1899, The American Institute of Architects chose the severely deteriorated building as its new national headquarters, initiating a series of state-of-the-art restorations.
