The Landsoldaten ("foot soldier") statue in Fredericia, Denmark.
Throughout history, many soldiers have died in numerous wars without their remains being identified. In modern times, nations have developed the practice of having a symbolic Tomb of the Unknown Soldier that represents the war grave of those unidentified soldiers. They usually contain the remains of a dead soldier who is unidentified (or "known but to God" as the stone is sometimes inscribed), thought to be impossible ever to identify so that he might serve as a symbol for all of the unknown dead wherever they fell. Much work goes into trying to find a certain soldier, and to verify that it is indeed one of the relevant nation's soldiers.
History
Perhaps the first memorial of this kind in the world is the 1858 Landsoldaten ("Foot Soldier") monument of the First War of Schleswig in Fredericia, Denmark. Another early memorial of this kind is the 1866 memorial to the unknown dead of the American Civil War.
They buried him among the kings Because he Had done good toward God and Toward His house[2]
Other nations followed this example. A famous tomb is the one in France under the Arc de Triomphe that was installed in 1921 honouring the unknown dead of the First World War, or the one in Ottawa, Ontario, Canada shadowed by the Canadian War Memorial.
These tombs are also used to commemorate the unidentified fallen of later wars. Monuments have been built as recently as 1982 in the case of Iraq, 1993 in the case of Australia, and 2004 in the case of New Zealand.
The Field of Honour is a memorial to unknown soldiers. There is also the Tomb of the Unknown (Dutch) Sailor in Kembang Kuning war cemetery in Surabaya.
