Coflein is the online database for the National Monuments Record of 
Wales (NMRW), the national collection of information about the historic 
environment of Wales. The name is derived from the Welsh cof (memory) 
and lein (line).
Coflein allows access to details of many 
thousands of archaeological sites, monuments, buildings and maritime 
sites in Wales, together with an index to the drawings, manuscripts and 
photographs held in the NMRW archive collections.
