#YourArchive – The Collections of the National Monument Record of Wales

The National Monuments Record of Wales is a huge, rich public archive built up by the Royal Commission since it was established under Royal Warrant in 1908 to investigate and record the archaeological and built heritage of Wales. The core of the NMRW are the site files arranged by historic county, site type, and OS. mapping (quarter sheets). In addition, there are other numerous separate collections listed below (not in alphabetical order).

Surveys, photographs, and inventories of sites across Wales were produced as part of this recording work. By the 1960s, with the addition of collections of material including national coverage of maps and aerial photographs, a huge amount of material had accumulated that required sorting, accessioning and cataloguing. In 1963 the National Monuments Record of Wales (NMRW) was officially set up.

Now an Accredited Archive, a Recognised Place of Deposit for Public Records and a MEDIN Digital Archive Centre, the National Monuments Record of Wales has 937 named collections; a number that is growing by the month as our own survey and investigation team feeds in material from their work and we continue to receive deposits from a wide range of heritage organisations and members of the public.

Giving highlights and examples from the archive never does justice to the scale and breath of the collections we hold, so to give some idea of the range of these collections they are listed in full below.

These records are all searchable online on our catalogue, Coflein, which allows you to delve further into each collection. Over 100,000 items, whether born digital or later digitised, are available to view freely.

If you are interested in finding out more about the archaeology, historic buildings, industrial and maritime heritage of Wales, perhaps as part of family and community history research, Coflein is an essential first port of call.

You can also come in person to our library and search room in Aberystwyth, or use our public enquiry service where specialist staff will provide information and help answer your enquiry.
