Defended Enclosure 350m E of Bank Green Grove is a prehistoric earthwork situated in Wales on Llandovery Rocks, geological formations of mudstone, siltstone and sandstone that date to the Llandovery period. The enclosure represents a settlement site from prehistory, defended by banks and ditches that would have provided protection and definition to the occupied area. Such earthwork enclosures are characteristic of Bronze Age and Iron Age settlement patterns across Britain and Wales, serving as both domestic and defensive structures.
The monument's construction exploited the local geology, with the bedrock providing a stable foundation for the defensive works. The combination of banks and ditches created a barrier that would have controlled access to the interior settlement space, typical of enclosed settlements of the later prehistoric period. The precise Llandovery geology—with its mixed sedimentary composition—would have offered varying ease of excavation for the ditch systems.
The site is protected by Cadw under reference CD272, ensuring its preservation as part of Wales's archaeological heritage. Such defended enclosures provide important evidence for prehistoric settlement patterns, community organisation and land use across the Welsh landscape during the Bronze and Iron Ages.
