The Tomb of the Unknowns is a monument dedicated to American service members who have died without their remains being identified. It is also known as the Tomb of the Unknown Soldier; it has never been officially named. It is located in Arlington National Cemetery in Virginia, United States of America. The World War I "Unknown" is a recipient of the Medal of Honor, the Victoria Cross, and several other foreign nations' highest service awards. The U.S. Unknowns who were interred are also recipients of the Medal of Honor, presented by the U.S. presidents who presided over their funerals.[1][2][3]

Tomb of 1921

Tomb as of November 11, 1922. The Tomb of 1931 would occupy this same location.

On March 4, 1921, the United States Congress approved the burial of an unidentified American serviceman from World War I in the plaza of the new Memorial Amphitheater. On November 11, 1921, the unknown soldier brought back from France was interred inside a three-level marble tomb. The marble came from a Yule Marble Quarry located near Marble, Colorado. The marble for the Lincoln Memorial and other famous monuments was quarried there.[4] The bottom two levels are six marble sections each and the top at least nine blocks with a rectangular opening in the center of each level through which the unknown remains were placed through the tomb and into the ground below. A stone other than marble covers the rectangular opening.[5][6][7]

Tomb of 1931

The World War I Unknown is below the marble sarcophagus. Other Unknowns are beneath the white slabs on the ground (World War II, right; Korean War, left). A Vietnam War Unknown was under the middle slab until 1998, when he was identified.

Since 1921 the intent was to place a superstructure on top of the Tomb, but it was not until July 3, 1926, that Congress authorized the completion of the Tomb and the expenditure of $50,000 (with a completed cost of $48,000). A design competition was held and won by architect Lorimer Rich[nb 1] and sculptor Thomas Hudson Jones. An appropriation from Congress for the work was secured and on December 21, 1929, a contract for completion of the Tomb itself was entered into. The Tomb would consist of seven pieces of marble in four levels (cap, die, base and sub-base) of which the die is the largest block with the sculpting on all four sides.[5][8]

In late January 1931, the 56 ton die of Yule marble (quarried 3.9 miles south of Marble, Colorado by the Vermont Marble Company) was lifted out of the quarry. (Only the die block is addressed for no data is available as to the other three levels). The quarrying involved 75 men working one year. When the block was separated from the mountain inside the quarry it weighed 124 tons. A wire saw was then brought into the quarry to cut the block down to 56 tons. On February 3, the block reached the marble mill site (in the town of Marble) where it was crated, then shipped to Vermont on February 8. The block was sawn to final size in West Rutland, Vermont and fabricated by craftsmen in Proctor, Vermont before it was shipped by train to Arlington National Cemetery, Virginia[9] where it was carved by the Piccirilli Brothers under the direction of the sculptor Thomas Jones.[5][10] (The brothers also carved the Lincoln statue for the Lincoln Memorial). The Tomb was dedicated in April 1932.[11]

The Tomb[nb 2] was placed at the head of the grave of the World War I Unknown. West of this grave are the crypts of Unknowns from World War II (south) and Korea (north). Between the two lies a crypt that once contained an Unknown from Vietnam (middle). His remains were positively identified in 1998 through DNA testing as First Lieutenant Michael Blassie, United States Air Force and were removed. Those three graves are marked with white marble slabs flush with the plaza.

The Tomb has a flat-faced form and is relieved at the corners and along the sides by neo-classical pilasters set into the surface with objects and inscription carved into the sides. The 1931 symbolism[10] of the objects on the north, south and east sides changed over time.[5][8]

North and South panel with 3 wreaths on each side represent (in 1931) "a world of memories" but later the six major battles engaged in by American forces in France; Ardennes, Belleau Wood, Château-Thierry, Meusse-Argonne, Oisiu-Eiseu, and Somme. Each wreath has 38 leaves and 12 berries.
East panel that faces Washington, D.C., are three Greek figures representing Peace, Victory, and "American Manhood" but later "Valor" instead of "American Manhood"
Western panel is inscribed the words (centered on the panel):

The Unknown of World War I

The World War I Unknown arriving at the Washington Navy Yard, 1921 (colorized)

On Memorial Day, 1921, four unknown servicemen were exhumed from four World War I American cemeteries in France. U.S. Army Sgt. Edward F. Younger, who was wounded in combat, highly decorated for valor and received the Distinguished Service Cross in "The Great War" selected the Unknown of World War I from four identical caskets at the city hall in Châlons-en-Champagne, France, on October 24, 1921.[7] Younger selected the World War I Unknown by placing a spray of white roses on one of the caskets. He chose the third casket from the left. The chosen Unknown was transported to the United States aboard the USS Olympia. Those remaining were interred in the Meuse Argonne Cemetery, France.[7]

The World War I Unknown lay in state in the Capitol Rotunda from his arrival in the United States until Armistice Day, 1921. On November 11, 1921, President Warren G. Harding officiated at the interment ceremonies at the Memorial Amphitheater at Arlington National Cemetery. During the ceremony, the World War I Unknown was awarded the Victoria Cross by Admiral of the Fleet Lord Beatty, on behalf of King George V of the United Kingdom.[13] (The United Kingdom Victoria Cross was placed with the soldier. Earlier, on March 4, 1921, the British Unknown Warrior was conferred the U.S. Medal of Honor by General of the Armies John Pershing.) In 1928, the Unknown Soldier was presented the Silver Buffalo Award for distinguished service to America's youth by the Boy Scouts of America.[14]

The Unknowns of World War II and Korea

The Korean War Unknown joins the two candidates from World War II aboard the USS Canberra

On August 3, 1956, President Dwight D. Eisenhower signed a bill to select and pay tribute to the Unknowns of World War II and the Korean War. The selection ceremonies and the interment of these Unknowns took place in 1958. The World War II Unknown was selected from remains exhumed from cemeteries in Europe, Africa, Hawaii, and the Philippines.[15]

Two Unknowns from World War II, one from the European Theater and one from the Pacific Theater, were placed in identical caskets and taken aboard the USS Canberra, a guided-missile cruiser resting off the Virginia Capes. Navy Hospital Corpsman 1st Class William R. Charette, then the U.S. Navy's only active-duty Medal of Honor recipient, selected the World War II Unknown. The remaining casket received a solemn burial at sea.[15]

Four unknown Americans who died in the Korean War were disinterred from the National Cemetery of the Pacific in Hawaii. Army Master Sergeant Ned Lyle made the final selection.[15]

Both caskets arrived in Washington on May 28, 1958, where they lay in the Capitol Rotunda until the morning of May 30, when they were carried on caissons to Arlington National Cemetery. President Eisenhower awarded each the Medal of Honor, and the Unknowns of World War II and the Korean War were interred in the plaza beside their World War I comrade.[15]

The Unknown of Vietnam

The designation of the Vietnam Unknown has proven to be difficult. With improvements in DNA testing it is possible, though unlikely, that the recovered remains for every unknown soldier killed in the Vietnam War will be identified.

The Vietnam Unknown service member was designated by Medal of Honor recipient U.S. Marine Corps Sgt. Maj. Allan Jay Kellogg, Jr., during a ceremony at Pearl Harbor, Hawaii, May 17, 1984.

The Vietnam Unknown was transported aboard the guided missile frigate USS Brewton (FF-1086) to Naval Air Station Alameda, California. The remains were then sent to Travis Air Force Base, California, May 24. The Vietnam Unknown arrived at Andrews Air Force Base, Maryland, the next day.

The Tomb guards stood at death watch for the entire day as thousands of people braved the dreary weather to pay their respects.

The presidential wreath was brought forward toward President Reagan during the interment ceremony for the Unknown Serviceman of the Vietnam Era at the Tomb of the Unknowns on May 28, 1984.

Many Vietnam veterans and President Ronald Reagan and Nancy Reagan visited the Vietnam Unknown in the U.S. Capitol. An Army caisson carried the Vietnam Unknown from the Capitol to the Memorial Amphitheater at Arlington National Cemetery on Memorial Day, May 28, 1984.

President Reagan presided over the funeral, and presented the Medal of Honor to the Vietnam Unknown, and also acted as next of kin by accepting the interment flag at the end of the ceremony. The interment flags of all Unknowns at the Tomb of the Unknowns are on view in the Memorial Display Room.

Identification of the Unknown

In 1994, Ted Sampley, a POW/MIA activist, determined that the remains of the Vietnam Unknown were likely those of Air Force 1st Lt. Michael Joseph Blassie, who was shot down near An Lộc, Vietnam, in 1972. Sampley published an article in his newsletter and contacted Blassie's family, who attempted to pursue the case with the Air Force's casualty office without result. In January 1998 CBS News broadcast a report based on Sampley's investigation which brought political pressure to support the identification of the remains.[16] The body was exhumed on May 14, 1998. Based on mitochondrial DNA testing, Department of Defense scientists confirmed the remains were those of Blassie. The identification was announced on June 30, 1998, and on July 10, Blassie's remains arrived home to his family in St. Louis, Missouri; he was reinterred at Jefferson Barracks National Cemetery on July 11.[17][nb 4]

Redesignation of the crypt

The slab over the crypt that once held the remains of the Vietnam Unknown has since been replaced. The original inscription of "Vietnam" and the dates of the conflict has been changed to "Honoring and Keeping Faith with America's Missing Servicemen." as a reminder of the commitment of the Armed Forces to fullest possible accounting of missing service members.

Tomb Guards

The tomb guards are soldiers of the United States Army's 3rd Infantry Regiment. It is considered one of the highest honors to serve as a Sentinel at the Tomb of the Unknowns. Fewer than 20 percent of all volunteers are accepted for training and of those only a fraction pass training to become full-fledged Tomb Guards. This attrition rate has made the Tomb of the Unknown Soldier Guard Identification Badge the second least-awarded decoration of the United States military (the first being the Astronaut Badge).[18]

The soldier "walking the mat" does not wear rank insignia, so as not to outrank the Unknowns, whatever their ranks may have been. Non-commissioned officers (usually the Relief Commander and Assistant Relief Commanders), do wear insignia of their rank when changing the guard only. They have a separate uniform (without rank) that is worn when they actually guard the Unknowns or are "Posted".

The duties of the sentinels are not purely ceremonial. The sentinels will confront people who cross the barriers at the tomb or who are disrespectful or loud.[19][20][21]


Over the years there have been several different types of weapons used by the Tomb Guards. The changes in weapons reflect the changes in the Army, including M1903 Springfield rifle, M1 Garand and M14 rifles, M1911 .45 ACP and M9 9mm Beretta pistols. Tomb Guards currently carry M14 rifles, which are unloaded and affixed to ceremonial rifle stocks (hand-made by Tomb Guards). These rifles are cleaned daily and kept ready for use at all times.[22]

Walking the mat

There is a meticulous routine which the guard follows when watching over the graves.[23] The Tomb Guard:

  1. Marches 21 steps south down the black mat laid across the Tomb.
  2. Turns and faces east, toward the Tomb, for 21 seconds.
  3. Turns and faces north, changes weapon to outside shoulder, and waits 21 seconds.
  4. Marches 21 steps down the mat.
  5. Turns and faces east for 21 seconds.
  6. Turns and faces south, changes weapon to outside shoulder, and waits 21 seconds.
  7. Repeats the routine until the soldier is relieved of duty at the Changing of the Guard.

After each turn, the Guard executes a sharp "shoulder-arms" movement to place the weapon on the shoulder closest to the visitors to signify that the Guard stands between the Tomb and any possible threat.

Twenty-one was chosen because it symbolizes the highest military honor that can be bestowed—the 21-gun salute.

The mat is usually replaced twice per year: before Memorial Day and before Veterans Day. This is required because of the wear on the rubber mat by the special shoes worn by Tomb Guards. The sentinels have metal plates built into the soles and inner parts of their shoes to allow for a more rugged sole and to give the signature click of the heel during maneuvers. The sentinels wear sunglasses because of the bright reflection from the marble surrounding the Tomb and the Memorial Amphitheater.

On the ground not covered by the mat, a wear pattern in the tile can be seen that corresponds to the precise steps taken during the changing of the guard. On the mat itself, footprints worn in by standing guard are also visible.

Changing of the Guard

During the day in summer months from April 1 to September 30, the guard is changed every half hour. During the winter months, from October 1 to March 31, the guard is changed every hour. After the cemetery closes to the public (7 p.m. to 8 a.m. April through September, and 5 p.m. to 8 a.m. October through March), the guard is changed every 2 hours. The ceremony can be witnessed by the public whenever Arlington National Cemetery is open.[24][25]

The guard change is very symbolic, but also conducted in accordance with Army regulations. The relief commander or assistant relief commander, along with the oncoming guard, are both required for a guard change to take place. The guard being relieved will say to the oncoming guard, "Post and orders remain as directed." The oncoming guard's response is always, "Orders acknowledged."


A civilian guard was first posted at the Tomb on November 17, 1925, to prevent, among other things, families from picnicking on the flat marble slab with views of the city. A military guard was first posted on March 25, 1926. The first 24-hour guard was posted on midnight, July 2, 1937. The Tomb of the Unknowns has been guarded continuously, 24 hours a day, 7 days a week, since that time.[26] Inclement weather,[27][28] terrorist attacks,[29] et cetera, do not cause the watch to cease.[30]

Since 1948, the Tomb Guards, a special platoon within the 3rd U.S. Infantry Regiment (The Old Guard) work on a team rotation of 24 hours on, 24 hours off, for five days, taking the following four days off. A guard takes an average of six hours to prepare his uniform – heavy wool, regardless of the time of year – for the next day's work. In addition to preparing the uniform, guards also conduct physical training, Tomb Guard training, participate in field exercises, cut their hair before the next work day, and at times are involved in regimental functions as well. Tomb Guards are required to memorize 16 pages of information about Arlington National Cemetery and the Tomb of the Unknown Soldier, including the locations of nearly 300 graves and who is buried in each one.[31]

A special Army decoration, the Tomb of the Unknown Soldier Guard Identification Badge is authorized for wear after passing a detailed test of 100 questions (from a pool of more than 300), a uniform test with two gigs (errors) or fewer (measured to the 1/64"), and a test on the guard changing sequence. After serving honorably for a period of nine months, and having passed the sequence of tests, a Tomb Guard is permanently awarded the Badge. Since the first award on February 7, 1958, fewer than 700 soldiers have completed training and been awarded this Badge, including three women. A small number of Tomb Guard Identification Badges have also been retroactively awarded to soldiers who served as Guards before 1959. Those numbers make the Badge the second rarest award currently issued in the United States Army; only the Army Astronaut Badge is rarer.[nb 5]

The badge was designed in 1956 and first issued to members of the Honor Guard at the Tomb of the Unknowns on February 7, 1958. The badge was first issued only as a temporary wear item, meaning the soldiers could only wear the badge during their tenure as members of the Honor Guard. Upon leaving the duty, the badge was returned and reissued to incoming soldiers. In 1963, a regulation was enacted that allowed the badge to be worn as a permanent part of the military uniform, even after the soldier's completion of duty at the Tomb of the Unknowns.

Damage and repair to the Tomb Monument

The crack can be seen underneath the words "An American" and above the word "Soldier."

President George W. Bush lays a wreath at the Tomb of the Unknown Soldier on Memorial Day.

Cracking and erosion are causing concerns for the long-term preservation of the Tomb Monument. A November 1963 report first recorded horizontal cracking of the monument's marble die block. Though this was the first time that the damage was documented, the report made it clear that the cracks had become visible some time before that date.[32]

In 1963–1964, there were two cracks—referred to as "primary" and "secondary"—extending approximately 34 feet around the die block. By 1974, they had extended to 40 feet. They grew another 4.6 feet over the next 15 years. Inspection has determined that the cracks have increased horizontally since 1990. Analysis also indicates that the cracks are not surficial but extend partially through the block and will eventually extend all the way through.[32]

The 1990 report documented deterioration of the marble's surface. As much as 2.85 mm of the marble surface has been lost through weathering. The study projected that before 2010, the Tomb Monument will have been eroded enough to have a negative effect on the experience of the visitors and concludes the only solutions are to enclose or replace the monument.[32]

Several options have been considered to deal with the damage. Officials at Arlington National Cemetery determined that proper repair can return the Tomb Monument to an acceptable appearance. However, because the cracks will continue to lengthen and widen, continuous grouting, regrouting, touch-up, monitoring, and maintenance would be required. Therefore, a report commissioned by Arlington National Cemetery and published in June 2006 confirmed the Cemetery's conclusion that "replacement of the three pieces of the Tomb Monument is the preferred alternative". A final decision was scheduled to be made on September 30, 2007.[32]

The National Trust for Historic Preservation objects to the plan to replace the authentic Tomb Monument. The Trust expressed concern that Arlington National Cemetery seeks to replace the existing monument with marble from the original quarry, which experts agree is likely eventually to crack.[33]

The Trust has observed that the Cemetery's own 1990 report recommended that the monument be repaired and that the Cemetery, in fact, commissioned Oehrlein Architects to repair the stone. In 2007, Mary Oehrlein informed Congressional staff members that: "The existing monument can easily be repaired, as was done 17 years ago, using conventional conservation methods to re-grout the cracks. Once repaired, the fault lines would be virtually invisible from the public viewing areas."[34][35]

On September 26, 2007, U.S. Senator Daniel Akaka announced that an amendment crafted together with Senator Jim Webb will be added to the National Defense Authorization Act for Fiscal Year 2008 (H.R. 1585) that would require a report on the plans of the Secretary of the Army and the Secretary of Veterans Affairs to replace the monument at the Tomb of the Unknowns. The secretaries would be required to advise Congress on the current efforts to maintain and preserve the monument. Additionally, they would have to provide an assessment on the feasibility and advisability of repairing rather than replacing the Tomb Monument. Finally, if the secretaries choose replacement, they would have to report those plans and detail how they intend to dispose of the current monument. Once the report is provided, the secretaries are prevented from taking action to replace the monument for at least 180 days. The Akaka-Webb amendment was included in the bill by unanimous consent of the Senate.[36] An amendment to the Fiscal Year 2008 Defense Authorization Bill authorized a review of the monument's condition. The bill also authorized repair, but not replacement, of the monument.[37] Final passage of the National Defense Authorization Act for 2008 (H.R. 4986) was signed by President Bush on January 28, 2008.

October 21, 2011: Completed repair of the cracks in the Tomb.

In 2003, retired Glenwood Springs, Colorado, car dealer John Haines donated a large slab of marble to the Arlington National Cemetery to replace the existing marble. Haines paid $31,000 for the marble slab.[38] The block though was not removed from the quarry because imperfections were found and was rejected. The heart of the block was used for a statue of President George H.W. Bush.[39] In 2005, a flawless replacement was quarried and brought down to the area where quarried blocks are kept awaiting transport to the customer. However, the marble has sat unused. "It's not doable. A citizen can't just give us any piece of marble and say, 'This is what we'll use to replace the tomb'", said Thurman Higginbotham, deputy superintendent of Arlington.[38] Haines's marble was cut from the same Yule Quarry where the original gold-veined marble for the Tomb of the Unknowns was mined nearly 80 years ago. The tomb replacement piece was cut after a nearly five-year search for an unflawed piece that would look like the original.[38] Arlington officials estimate the cost of replacing the tomb's marble at $2.2 million: $80,000 of that for seeking bids, $90,000 for buying and transporting the marble and the remainder for sculpting. Haines's donated marble includes free shipping that he arranged himself.[38]

In June 2009 Arlington National Cemetery and The Army Corps of Engineers announced that the monument was to be repaired, not replaced.[40] In 2010, the cracks were filled but the repairs lasted only a few months.[41] As of June 2011, the cemetery was struggling to repair the cracks in the monument, one of which measured 28.4 feet long, with another at 16.2 feet.[42] In September 2011, the cracks were filled again[41] and an October 21, 2011, inspection by the Army Corps of Engineers and other experts pronounced the repairs a success.[43]

The Unknowns documentary

Two former soldiers, Neal Schrodetzki and Ethan Morse collaborated to film a documentary about the Old Guard and the Tomb of the Unknowns.[44] They used a Kickstarter campaign to raise the funds for the movie.[45] The film is scheduled to begin showing in film festivals in 2014.
