Gwerclas cairn has never , as far as we know been excavated therefore classification has largely depended on a series of observations and surveys . Despite having been lately identified as a Bronze Age round Barrow it displays all the features of having been constructed at some time during the Neolithic period .
It appears to be what in archaeological terms is called a Chambered Tomb – a Long Barrow
The long Barrows were funerary monuments of the Neolithic . The chambers of the barrows were often covered by capstones and burials were deposited over a period sometimes over a thousand years . They sometimes show evidence of ceremonial and ritual use .Excavations elsewhere have shown that fires were lit outside the tombs and deposits of animal and human bone have been discovered in a ‘ritual’ context .
Gwerclas is a large , long mound which is somewhat denuded through the activity of erosion and farming over a long period
The kerbstones above indicate the entrance may have been in this area of the body of the cairn.
The location of the Gwerclas tomb is interesting . The monument lies near to the River Dee and a historic crossing point .Views to the river from the cairn indicate that the River was possibly a focal point for the tomb builders .
A possible Neolithic ceremonial cursus monument has been identified across the Dee from Gwerclas at SJ06204343 and is known as the Corwen Cursus . The cursus runs for approximately 120 metres on a SSW-NNE alignment. The ditches are around 27m apart and there is a ring ditch close to the northern end.
The burial site may have been somehow linked to the cursus in some way although any theories have to be conjectural in the light of an excavation evidence which links the two .
The implications for a developed ritual landscape in this area are the focus for further research.
