Pentre Ifan is one of the most impressive Neolithic monuments in Wales — a burial chamber built around 3500 BCE on the northern slopes of the Preseli Hills, about 15 kilometres east of Fishguard. The massive blue-grey capstone, balanced on three tall pointed uprights, has been in place for over 5,000 years and is remarkably well preserved.
The site is maintained by Cadw (Welsh Historic Monuments) and is free and open at all times. The surrounding landscape — rolling hill farmland with views north to the coast and south to the Preseli ridgeline — adds to the sense of place. The Preseli Hills were the source of the bluestones used at Stonehenge, transported some 225 kilometres across Wales and the Severn by methods still debated. Pentre Ifan gives a powerful sense of the culture that moved them.
