Corwen and Dee Valley Archaeological Society was founded in order to research, promote and share the rich archaeological heritage of the Dee Valley and surrounding area .
It is the aim of the society to research and record through desktop studies and fieldwork the archaeological landscape of the Dee Valley from around 5000BC through to the post medieval period .
The earliest surviving monuments represented in the Dee Valley are the funerary monuments Tan y Coed, Cynwyd, being the best preserved example and probably dating to the earlier / middle neolithic .
Surveys undertaken by CPAT / Clwyd Powys Archaeological Trust indicate that certain areas were favoured as what we term Funerary and Ritual Landscapes . This is apparent in the Llandrillo area with the occurrence of stone circles, tombs and reference to a cursus monument . The landscape for whatever reasons which are lost to us held deep significance for the people who lived here in the Neolithic and Bronze Age . The chambered cairns and stone circles represent a ritual landscape of archaeological importance and worthy of further research, investigation and analysis.
