Arlington National Cemetery is a United States military cemetery in Arlington County, Virginia, across the Potomac River from Washington, D.C., in whose 624 acres (253 ha) the dead of the nation's conflicts have been buried, beginning with the Civil War, as well as reinterred dead from earlier wars. The United States Department of the Army, a component of the United States Department of Defense (DoD), controls the cemetery. The national cemetery was established during the Civil War on the grounds of Arlington House, which had been the estate of Confederate general Robert E Lee's wife Mary Anna Custis Lee (a great-granddaughter of Martha Washington). The Cemetery, along with Arlington House, Memorial Drive, the Hemicycle, and the Arlington Memorial Bridge, form the Arlington National Cemetery Historic District, listed on the National Register of Historic Places in April 2014.

The United States Marine Corps War Memorial (Iwo Jima Memorial) is a national memorial located in Arlington County, Virginia, in the United States. Dedicated in 1954, it is located in Arlington Ridge Park with George Washington Memorial Parkway, near the Ord-Weitzel Gate to Arlington National Cemetery and the Netherlands Carillon. The war memorial is dedicated to all U.S. Marine Corps personnel who died in the defense of the United States since 1775. The memorial was inspired by the iconic 1945 photograph of six Marines raising a U.S. flag atop Mount Suribachi during the Battle of Iwo Jima in World War II taken by Associated Press combat photographer Joe Rosenthal. Upon first seeing the photograph, sculptor Felix de Weldon created a maquette for a sculpture based on the photo in a single weekend at Patuxent River Naval Air Station in Maryland, where he was serving in the Navy. He and architect Horace W. Peaslee designed the memorial. Their proposal was presented to Congress, but funding was not possible during the war. In 1947, a federal foundation was established to raise funds for the memorial.

The United States Air Force Memorial honors the service of the personnel of the United States Air Force and its heritage organizations. The Memorial is located in Arlington County, Virginia, on the grounds of Fort Myer near The Pentagon, and adjacent to Arlington National Cemetery, towards intersection of Columbia Pike and South Joyce Street. It was the last project of American architect James Ingo Freed (known for the design of the United States Holocaust Memorial Museum) with the firm Pei Cobb Freed & Partners for the United States Air Force Memorial Foundation.

The United States Capitol, often called the Capitol Building, is the home of the United States Congress and the seat of the legislative branch of the U.S. federal government. It is located on Capitol Hill at the eastern end of the National Mall in Washington, D.C. Though no longer at the geographic center of the Federal District, the Capitol forms the origin point for the District's street-numbering system and the District's four quadrants. The original building was completed in 1800 and was subsequently expanded, particularly with the addition of the massive dome, and expanded chambers for the bicameral legislature, the House of Representatives in the south wing and the Senate in the north wing. Like the principal buildings of the executive and judicial branches, the Capitol is built in a distinctive neoclassical style and has a white exterior. Both its east and west elevations are formally referred to as fronts, though only the east front was intended for the reception of visitors and dignitaries.

The United States Navy Memorial is the triumph of a centuries-old dream for America’s Sea Services. When architect Pierre L'Enfant designed Washington, DC, he envisioned a memorial that would celebrate the rich heritage of the United States Navy, dating back to 1775 when a force of eight small wooden ships fought and won its first battle at sea. L'Enfant's vision would be realized over two hundred years later. Navy legend and former Chief of Naval Operations (CNO) Admiral Arleigh Burke decided there was enough “talk” about a Navy Memorial and that it was time to act. Burke and his Navy colleagues, including former Chairman of the Joint Chiefs of Staff Admiral Tom Moore and former Chief of Naval Operations (CNO) Admiral Elmo "Bud" Zumwalt worked together to form a non-profit organization called the “United States Navy Memorial Foundation” in the spring of 1977.
