The Mari Lwyd: Wales' Most Mysterious Christmas Tradition
by: The Bauble.me Christmas Elves

What is the Mari Lwyd?
The Mari Lwyd (pronounced "MAH-ree-LH-oyd") is one of Wales' most ancient and mysterious Christmas traditions. Dating back centuries, this haunting custom involves a group of wassailers carrying a decorated horse skull mounted on a pole, covered with a white sheet, and adorned with ribbons, bells, and sometimes coloured glass eyes.
The name translates to "Grey Mare" in English, and this spectral figure would travel from house to house during the Christmas season, accompanied by a small party of followers including musicians and singers.
The Pwnco: A Battle of Wits
The most fascinating aspect of the Mari Lwyd tradition is the "pwnco" - a battle of rhyming insults and wit conducted entirely in Welsh verse. The Mari Lwyd party would arrive at a house and challenge the occupants to this poetic duel through the closed door.
The householders would respond with their own verses, trying to prevent the Mari Lwyd from entering. This could go on for quite some time, with both sides trading increasingly creative and humorous insults in traditional Welsh metres.
The goal: If the Mari Lwyd party could out-rhyme the householders, they would be invited in for food, drink, and celebration. If the householders won, the Mari Lwyd would move on to the next house.
Modern Mari Lwyd Celebrations
Where to See It
The tradition is still alive in parts of South Wales, particularly around Swansea, Neath, and the Gower Peninsula. Some pubs and cultural centres also host Mari Lwyd events during the Christmas season.
Cultural Revival
After nearly dying out in the mid-20th century, the Mari Lwyd has experienced a revival, with new groups forming and adapting the tradition for modern times while respecting its ancient roots.
Creating Your Own
While traditionally using a real horse skull, modern versions often use carved wood or other materials. The key elements are the white sheet, ribbons, bells, and the spirit of fun and community.
The Christmas Connection
Though pre-Christian in origin, the Mari Lwyd became associated with Christmas and New Year celebrations, representing themes of death, rebirth, and the turning of the year.
