Caer Allt-Goch Hillfort is a prehistoric fortified settlement located in Wales and protected as a scheduled ancient monument under Cadw reference CD169. The site occupies ground underlain by the Llandovery Rocks, a formation of mudstone, siltstone and sandstone from the early Palaeozoic era. These varied bedrock conditions would have shaped both the hillfort's construction and the landscape available to its inhabitants.
Hillforts of this type, typically dating to the Iron Age, were established as defended settlements and gathering places. Their siting on elevated terrain provided natural defensive advantages, and the strategic positioning would have allowed occupants to control movement across the surrounding countryside. The specific geology of the Llandovery formation, with its mixture of softer and harder stone, influenced how defences could be constructed.
Caer Allt-Goch remains a significant record of prehistoric Welsh settlement patterns and defensive strategies. Its protected status recognises the archaeological importance of the monument, which contributes to understanding Iron Age communities in Wales and the broader patterns of fortified settlement across the region during this period.
