Pentre Ifan (Welsh for 'Ifan's village') is an ancient dolmen in the community and parish of Nevern, Pembrokeshire in Wales. It contains and gives its name to the largest and best preserved neolithic dolmen in Wales.
The Pentre Ifan monument is a scheduled monument and one of three Welsh monuments to receive legal protection under the Ancient Monuments Protection Act 1882. Pentre Ifan’s sense of mystery is heightened by its surroundings and backdrop. Its outline neatly frames the Preseli Hills towering above, source of the famous Pembrokeshire ‘bluestones’ that went into the making of Stonehenge as well as Pentre Ifan itself.
