Contrary to many other exciting archaeological monuments, Le Déhus is located in a rather unromantic setting - in a sharp bend of street opposite the market garden in the densely populated island of Guernsey. This monument has been extensively excavated and a lot here has been rebuilt and reconstructed. Nevertheless this is magnificent and enigmatic monument of history.
Much explored, much altered
Current name of this passage grave - "Déhus" - most likely comes from the Old Norse dys - a mound, barrow. Thus the origin of this mound was not a secret in medieval times.
In the early 19th century and earlier Le Déhus was not covered with a soil - it was a bare heap of stones. These stones in the 18th century became an object of desire to local quarrymen. Just in time some John de Havilland saved the mound in 1775 - he purchased the stones to keep them intact.
First known excavations here took place already in 1837 - 1847 - these works were organized by F.C.Lukis and his family. They found that this aggregation of stones really hides a prehistoric passage grave. Unfortunately the results of these excavations have not been oficially published.
There have been more excavations in Le Déhus - by Rev. G.E.Lee in 1898 , by Col. T.W.M. de Guerin in 1915.
In 1932 there were organized excavations by Miss V.C.C. Collum - it was after these works when this ancient stone setting was covered with a mound.
In fact the numerous explorers of this passage grave were keen to restore also the chambers of passage - but, unfortunately, each of them did it with some alterations and now we don't know how the original passage grave looked. Thus nowadays Le Déhus is not as authentic as, for example, such wonderful monument as La Hougue Bie in the nearby Jersey Island.
Burial mound with mysterious standing stone
Diameter of the mound now is 20 m. Mound is made in the 20th century - but the surrounding stones at least partly have been preserved from the original, Neolithic mound. It is known that sometimes around 1844 there were at least 19 of these stones intact.
Interesting feature is lots of limpet shells inside the grave. There is hypothesis that this monument has been built in a shell midden.
The entrance in the grave is oriented towards the north-east - towards the sea.
Narrow passage, almost 3 m long and just 1 m wide, leads into the mound - after squeeezing through it one finds himself in a broad chamber. This chamber is 6 m long and up to 3.5 m wide. Walls are made by large, closely fitting upright stones. It is possible that originally it was roofed with four giant capstones. Three original capstones remain.
Chamber has four side chambers. Two of these chambers are modern reconstructions and do not reflect original structure.
Unique feature of Le Déhus is a standing stone in the middle of chamber - it almost reaches a capstone. It is not completely clear, what is the original purpose of this stone - may be it was an attempt to prevent the capstone from fracturing (capstone in fact fractured and was repaired in the 19th century). But it is possible that this upright stone holds some symbolic meaning.
Archaeological findings show that Le Déhus certainly was used for burials.
Lukis found on the floor lots of human ashes and bones, skeletons, stone and bone tools, shards of pottery. There were recovered also 7 or 8 pottery vessels - all located near a mysterious upright pillar in the main chamber of the passage grave.
In one chamber there were found multiple layers of human burials - this hints at the fact that this monument was used for extended period of time.
Especially puzzling is one finding: in a very narrow right hand chamber F.C.Lukis found two male skeletons. These people died standing upright on knees - their bones were fixed in this position by the accrued ground and limpet shells. It looks like these people were buried here alive.
Le Gardien du Tombeau
It is amazing that the most amazing value of Le Déhus was not noticed by F.C.Lukis, although he worked in the site for ten years. This unique feature - prehistoric stone carving - was hidden - the second capstone of passage grave was broken and lying on the ground. Later - in 1898 - capstone was repaired with wire but: again the image was not noticed.
Only in 1917 there was discovered an image of bearded man holding a bow and arrows on the surface of capstone. This artwork was named Le Gardien du Tombeau - guardian of the tomb.
Carving was done before the stone was broken - the lines are seen on both parts of the stone.
Parts of the carving of Le Gardien are hidden beneath the support stone - thus almost certainly this is an older monument, brought here. It is possible that this was a standing stone - earlier megalithic monument.
