Created by Congress in 2020 to honor the 250th anniversary of the United States, the Semiquincentennial Grant Program funds restoration and preservation for sites and structures listed on the National Register of Historic Places that commemorate the founding of this nation. 

“The Octagon stands as a testament to America’s architectural heritage and our nation’s early history,” said Architects Foundation Director, Jennifer Calvert Hall. “This grant enables us to undertake critical preservation work that will ensure future generations can experience this remarkable building and learn about the vital role architecture plays in our national story.” 

Hall emphasized that this National Park Service grant marks the beginning of a broader initiative. “This significant award kicks off our comprehensive campaign for The Octagon’s renewal—a transformative effort that will not only preserve this National Historic Landmark but also enhance its capacity to serve the public as a premier center for architectural education and design literacy.” 

Historic Significance and Architectural Innovation 

The Octagon holds an extraordinary place in both American architectural and political history. Designed by Dr. William Thornton, the architect of the U.S. Capitol, and built between 1799 and 1801, The Octagon served as the official residence for President James Madison and First Lady Dolley Madison following the burning of the White House during the War of 1812. 

One of the first National Historic Landmarks listed on the National Register of Historic Places, The Octagon is significant for its distinctive, geometric Federal design and its direct connections to the founding era of Washington, D.C. 

Leading Preservation Innovation 

In 1902, The Octagon was purchased by the American Institute of Architects (AIA) to serve as the organization’s headquarters. The AIA’s comprehensive rehabilitation of the then-century-old building was among the first major preservation projects in the United States, establishing important precedents for historic building conservation. 

Since 2006, The Octagon has served as headquarters for the Architects Foundation, the official philanthropic partner of the AIA. As a cornerstone of Washington, D.C.’s AIA Global Campus for Architecture & Design, The Octagon serves as both a historic landmark and active museum hosting exhibitions, educational programs, and events that connect the architecture profession with the public. 

The structural stabilization project will address critical building systems while ensuring The Octagon’s continued role as an active museum, educational center, and showcase for historic preservation. This investment supports The Octagon’s expanding role in architectural education and its position as a premier destination for design professionals and the public. 

This project is supported in part by a Semiquincentennial grant from the Historic Preservation Fund administered by the National Park Service, Department of the Interior.
