The site occupies a prominent hilltop position and is defined by defensive earthworks characteristic of Iron Age settlement patterns in Wales, though precise dating requires archaeological investigation. The monument comprises substantial banks and ditches that would have provided protection and visual dominance over the surrounding landscape, typical of fortified settlements used during the later prehistoric period. As a scheduled ancient monument under Cadw's protection, the site remains an important archaeological resource for understanding Iron Age settlement and territorial organisation in the region.
