Holyhead Mountain Hut Circles

Holyhead Mountain Hut Circles are remains of about two dozen stone-built roundhouses scattered across a natural mountainside slope. The walls still stand to about one meter in height and vary in size, with some structures reaching diameters of up to 8 meters.

The site was inhabited by people over many thousands of years, with evidence of settlement from the late third millennium BC through the Roman period. Archaeological work since the 1800s has revealed insights into this long history of occupation.

The roundhouses reflect Iron Age building traditions, with stone construction and thoughtful room layouts. Visitors can see today how people arranged their spaces for daily life and storage when walking through the remains.

The site sits on a mountainside and is open year-round for visitors to walk the grounds and explore the structures. Good footwear and wind and rain protection are helpful, as the location is exposed and weather can change quickly.

Some buildings still preserve traces of internal divisions, hearths, and built-in furniture such as benches and storage pits today. These details offer rare glimpses into how people arranged and used their living spaces in prehistoric times.
