The Tomb of the Unknown Warrior

In Westminster Abbey, there is a single grave covered by a large slab of black marble. It has the interesting distinction, I've been told, of being the only grave in the Abbey that visitors are specifically forbidden to walk on. In it rests the body of a British soldier slain in World War I, chosen in such a manner to specifically make it unknown what battlefield he came from, exactly when he was killed, or even what branch of the military he was from. On the stone is inscribed the following:

BENEATH THIS STONE RESTS THE BODY
OF A BRITISH WARRIOR
UNKNOWN BY NAME OR RANK
BROUGHT FROM FRANCE TO LIE AMONG
THE MOST ILLUSTRIOUS OF THE LAND
AND BURIED HERE ON ARMISTICE DAY
11 NOV: 1920, IN THE PRESENCE OF
HIS MAJESTY KING GEORGE V
HIS MINISTERS OF STATE
THE CHIEFS OF HIS FORCES
AND A VAST CONCOURSE OF THE NATION

THUS ARE COMMEMORATED THE MANY
MULTITUDES WHO DURING THE GREAT
WAR OF 1914 - 1918 GAVE THE MOST THAT
MAN CAN GIVE LIFE ITSELF
FOR GOD
FOR KING AND COUNTRY
FOR LOVED ONES HOME AND EMPIRE
FOR THE SACRED CAUSE OF JUSTICE AND
THE FREEDOM OF THE WORLD

THEY BURIED HIM AMONG THE KINGS BECAUSE HE
HAD DONE GOOD TOWARD GOD AND TOWARD
HIS HOUSE

Around the main inscription are four texts:

THE LORD KNOWETH THEM THAT ARE HIS (top)
UNKNOWN AND YET WELL KNOWN, DYING AND BEHOLD WE LIVE (side)
IN CHRIST SHALL ALL BE MADE ALIVE (base)
GREATER LOVE HATH NO MAN THAN THIS (side)
