Visitor Notice

Due to concerns over the further spread of Coronavirus and the well-being of our visitors, we regret to report that all Cadw unstaffed monuments and car parks will be closed from 5pm Monday 23 March until further notice. We do look forward to inviting people to once again enjoy these outstanding monuments as soon as we are able.

Overview

Iron Age settlement in a spectacular mountaintop location

Perched at the summit of Holyhead Mountain with expansive views in all directions, it’s easy to see why our Iron Age ancestors chose this spot. The rampart walls still stand 10ft/3m high and 14ft/4m thick in places, merging with the mountain’s rocky terrain to create what must have been an imposing fortification. The remains of the walls’ original internal walkway and narrow, funnelled entrance, set within a deep rocky gully, can still be seen today.

Though the massive enclosure circles an area of around 17 acres/6.9ha, the only structure found inside is the ruin of a later Roman watchtower and signal station, possibly linked to the nearby coastal fort at Caer Gybi.
