History & significance

Castell-y-Gaer is a prehistoric enclosure situated in Carmarthenshire, Wales, representing an important example of Iron Age fortified settlement in South Wales. The site consists of a substantial earthwork comprising multiple defensive banks and ditches that enclose an elevated position, characteristic of hill fort construction during the later prehistoric period. Its strategic location and defensive features suggest it served as a territorial stronghold and possibly a centre for regional authority during the Iron Age.
