In the late 1990s Dyfed Archaeological Trust rapidly surveyed historic churches in Carmarthenshire, Ceredigion and Pembrokeshire as part of a pan-Wales survey, grant-aided by Cadw and carried out by the four Welsh archaeological trusts.

The aim of the project was to provide a record of all pre-nineteenth-century churches under the ownership of the Church in Wales. Churches rebuilt in the nineteenth century on the site of earlier churches were also recorded. Redundant churches and deserted church sites were not recorded.
In total 273 churches were recorded in the three counties. Information on these is provided here.
In addition county overview reports were produced, with Pembrokeshire split into two reports, north Pembrokeshire and south Pembrokeshire.
The reports on individual churches and the county summaries are only available in English.
