This selection of photographs has come from the Royal Commission on the Ancient and Historical Monuments of Wales in Aberystwyth, a research source for anyone delving into the nation's past. With over a million photographs and thousands of maps and drawings, it is a treasure trove of Welsh archaeology and history available to all.
A major current initiative is the development of Coflein, an online database with details of many thousands of archaeological sites, historic buildings and maritime heritage locations in Wales.
