There are detailed records on historic assets in Wales to provide information to owners, statutory bodies and others about what is protected and whether this protection is statutory or not. 

Cadw holds records on protected monuments, structures, landscapes and marine sites in Wales. Information is supplied to owners, statutory bodies, stakeholders and partners. Cadw works with a number of partner organisations, such as local authorities. Both Cadw and local authorities hold information concerning listed buildings and buildings at risk.

Cadw, the Royal Commission on the Ancient and Historical Monuments of Wales, Amgueddfa Cymru - National Museum Wales and the four Welsh Archaeological Trusts all provide information for an online resource called the Historic Wales Portal. The portal provides an overview of the records held by each organisation – including listed buildings and scheduled ancient monuments.

Historic Wales is hosted by the Royal Commission on the Ancient and Historical Monuments of Wales. The Commission also curates the National Monuments Record of Wales (NMRW), which is the national collection of information about the historic environment of Wales from the earliest times to the present day. Coflein is the online database for the NMRW, which allows access to details of many thousands of archaeological sites, monuments, buildings and maritime sites in Wales. There is also an index to the drawings, manuscripts and photographs held in the NMRW archive collections.
The name is derived from the Welsh cof (memory) and lein (line).

The four Welsh Archaeological Trusts are regionally based organisations. Each trust holds a historic environment record. These historic environment records fulfil a wide variety of functions including assisting the positive management and presentation of the historic landscape, planning control, and as a source for local history, conservation and tourism projects. Online access to information for all of the historic environment records can be found at Archwilio.

Archwilio translates as to explore, examine or audit and therefore encapsulates the use of the historic environment records in relation to the historic environment.
