Quarters 1 (Fort Myer)

Joint Base Myer–Henderson Hall is a Joint Base of the United States military that is located around Arlington, Virginia which is made up of Fort Myer (Arl), Fort McNair (SW DC), and Henderson Hall. It is the local residue of the Base Realignment and Closure, 2005 process. It is commanded by the United States Army but has resident commands of Army, Navy, & Marines. Most conspicuous is the Arlington National Cemetery Honor Guard. The two eponymous bases are co-located along the west boundary of the cemetery, and Fort McNair is across the Potomac River, in Washington, DC, on the Anacostia River. On Fort McNair sits Grant Hall which is the location of the 1865 military tribunal of the conspirators of the assassination of Abraham Lincoln. Each quarter the Hall is open to the public where people can visit the courtroom and learn more about the trials.

Fort Myer is the previous name used for a U.S. Army post next to Arlington National Cemetery in Arlington County, Virginia, and across the Potomac River from Washington, D.C. Founded during the American Civil War as Fort Cass and Fort Whipple, the post merged in 2005 with the neighboring Marine Corps installation, Henderson Hall, and is today named Joint Base Myer–Henderson Hall.

The brick buildings are in the Colonial Revival style, with some fenestration elements influenced by the Art Deco and Moderne style.It was listed on the National Register of Historic Places in 2004.

The Arlington Line was a series of fortifications that the Union Army erected in Alexandria County (now Arlington County), Virginia, to protect the City of Washington during the American Civil War (see Civil War Defenses of Washington and Washington, D.C., in the American Civil War).Just across the Potomac River from the Union capital city, Confederate Virginia was a major Union concern when the war began. In May 1861, federal troops seized much the County and immediately began constructing a group of forts near Washington on the Virginia side of the River to protect the capital city. After the Confederate Army routed the Union Army at the First Battle of Bull Run (Manassas) in late July 1861, the Union Army began construction on a line of breastworks and lunettes to the west of the earlier fortifications. These and larger fortifications later constructed nearby became known as the Arlington Line. They included a lunette (Fort Cass) and Fort Whipple, which became parts of Fort Myer, later to be renamed as Joint Base Myer–Henderson Hall. The Arlington Line was never attacked, even after the federal defeat at the Second Battle of Bull Run (Manassas) in late August 1863. The Line therefore effectively served its strategic purpose. Major Daniel Phineas Woodbury was the Union engineer who designed and constructed the Arlington Line. One of its forts, Fort Woodbury (which once stood in what is today Arlington's Courthouse neighborhood), was named for him.

Fort Woodbury was part of the Arlington Line, an extensive network of fortifications erected in present-day Arlington County, Virginia to protect Washington, D.C. from Confederate attack during the American Civil War. Construction began on the Arlington Line in May 1861, shortly after war broke out, and accelerated after the Union's defeat at the First Battle of Bull Run in July 1861.

The Confederate Memorial is a memorial in Arlington National Cemetery in Arlington County, Virginia, in the United States, that commemorates members of the armed forces of the Confederate States of America who died during the American Civil War. Authorized in March 1906, former Confederate soldier and sculptor Moses Jacob Ezekiel was commissioned by the United Daughters of the Confederacy in November 1910 to design the memorial. It was unveiled by President Woodrow Wilson on June 4, 1914 (the 106th anniversary of the birth of Jefferson Davis, the President of the Confederate States of America). The memorial grounds have changed slightly due to burials and alterations since 1914. Some major changes to the memorial were proposed over the years, but none has been implemented. Since the memorial's unveiling, most United States presidents have sent a funeral wreath to be laid at the memorial every Memorial Day. Some presidents have declined to do so, and the tradition is controversial. Since Arlington National Cemetery is operated by United States Department of the Army, The Naming Commission identified the monument as something that is under its purview in March 2022 and the Secretary of Defense may ultimately have to determine its fate.

Arlington House, The Robert E. Lee Memorial, formerly named the Custis-Lee Mansion, is a Greek revival style mansion located in Arlington, Virginia, United States that was once the home of Confederate Army General Robert E. Lee. It overlooks the Potomac River and the National Mall in Washington, D.C. During the American Civil War, the grounds of the mansion were selected as the site of Arlington National Cemetery, in part to ensure that Lee would never again be able to return to his home. The United States has since designated the mansion as a National Memorial. Although the United States Department of the Army controls Arlington National Cemetery, the National Park Service, a component of the United States Department of the Interior, administers Arlington House.

The James Tanner Amphitheater is a historic wood and brick amphitheater located at Arlington National Cemetery in Arlington County, Virginia, in the United States.

The amphitheater was informally called the Old Amphitheater from 1920 to May 2014, when it was renamed the James R. Tanner Amphitheater in honor of James R. Tanner, a disabled American Civil War veteran and influential veterans' organization leader.

The Civil War Unknowns Monument is a burial vault and memorial honoring unidentified dead from the American Civil War. It is located in the grounds of Arlington House, The Robert E. Lee Memorial, at Arlington National Cemetery in Arlington, Virginia, in the United States. It was designed by Quartermaster General Montgomery C. Meigs and constructed in 1865. Many sources often incorrectly state that the monument was constructed in the middle of the Lee flower garden (often mischaracterized as a "rose garden"). However, the monument is just west of the flower garden, in what was once a grove of oak and elm trees.

The Rough Riders Memorial is a memorial in Arlington National Cemetery in Arlington County, Virginia, in the United States that commemorates those members of the "Rough Riders" who died in the Spanish–American War in 1898. The grey granite shaft was erected by surviving members of the Rough Riders and their friends and supporters. Although Arlington National Cemetery, a number of secondary sources, and even the bronze plaque on the memorial say the monument was dedicated in 1906 and one source says 1905, contemporary newspaper accounts show the memorial was dedicated on April 12, 1907.
