Excavations between 1984 and 1989 focused on two areas within the hillfort of Caer Cadwgan. Trench A examined the main rampart and an associated gateway which was later blocked following an extensive fire, as well as various internal contexts. Trench B extended across part of the interior, identifying several house platforms, one with up to at least five structural phases. The material culture from the site indicates that a wide range of activities was being undertaken, while the charred plant remains and animal bones provide valuable detail about the local economy. Radiocarbon dating demonstrates that occupation was concentrated in the third and fourth centuries BC, though one date shows that it may have continued into the second or first half of the first century BC.
