The proposed triumphal arch is meant to commemorate the United States’ 250th birthday. It was proposed by Pres. Donald Trump and is scheduled to stand 250 feet (76,2 meters) tall. At that height it would be the third tallest building on the National Mall and more than twice the height of the Arc de Triomphe in Paris. Concerns have arisen about its size, the way it would impact sight lines from Arlington National Cemetery to the National Mall, lack of congressional oversight and cost. In September 2026, Trump said the arch would be used as a “military complex” housing snipers and drones.
