List of prehistoric scheduled monuments in Carmarthenshire
# List of prehistoric scheduled monuments in Carmarthenshire

Carmarthenshire is a large rural county in West Wales. It includes mix of upland and mountainous terrain and fertile farmland. The western end of the Brecon Beacons National Park lies within the county. Across Carmarthenshire there are a total of 370 Scheduled monuments, which is too many for a single list page. For convenience the list is divided into the 227 prehistoric sites (shown below) and the 143 Roman to modern sites. Included on this page are small number of stone chambered tombs from the Neolithic. There are a large and diverse variety of burial cairns, mounds and barrows, mainly from the Bronze Age, accounting for 197 sites. A further 49 Iron Age sites are mostly defensive sites such as hillforts and enclosures. Carmarthenshire is both a unitary authority and a historic county. Between 1974 and 1996 it was merged with Cardiganshire (now Ceredigion) and Pembrokeshire to form Dyfed.

All the Roman, early medieval, medieval and modern sites are listed at List of Scheduled Roman to modern Monuments in Carmarthenshire
