Halloween Stories: Calan Gaeaf — When Spirits Roam In Wales

Before the modern Halloween came back to the British Isles, there were celebrations like the Welsh Calan Gaeaf. The first day of winter. The night before this day was when the veil was thinnest and the spirits roamed the land.

Home, home, at once
The tailless black sow shall snatch the last one.
– Welsh rhyme from Nos Calan Gaeaf

As the winds of autumn grow colder and the days shorter, the people of Wales prepare for Calan Gaeaf, a festival steeped in ancient tradition and eerie folklore. Celebrated on the night of October 31st, this Celtic holiday marks the transition into winter—when the veil between the living and the dead thins, allowing spirits to walk freely among the living.

Much like its more famous counterpart, Halloween, Calan Gaeaf is a time when ghostly apparitions and supernatural forces are said to roam the earth. But in Wales, the night is uniquely filled with tales of terrifying spirits, haunted crossroads, and ominous signs of death. It’s a night where even the bravest avoid stepping outside after dark.

The Origins of Calan Gaeaf Festivities

Before the modern Halloween came back to the British Isles, there were celebrations like the Welsh Calan Gaeaf. The first day of winter. The night before this day was when the veil was thinnest and the spirits roamed the land. — **Harvest**: The Calan Gaeaf is a harvest festival as well, and things like apple bobbing and telling fortune of apple skin were some of the activities.

Calan Gaeaf, translating to “the first day of winter” in Welsh, has roots in the ancient Celtic festival of Samhain. For the Celts, this night represented the end of the harvest season and the start of the dark half of the year, when the world was gripped by cold and the dead returned to walk among the living. Or is it really a tradition for all Celts? There are those who claim there really is no evidence that Samhain was ever celebrated in Wales, making some think it is more a Gaelic custom rather than Celtic.

But how far does this celebration date back though? The word, Galan or Calan is actually from the latin, calends “first day of winter.”

What is Celtic though is the dating of the day. The night before the day is called the Nos Galan Gaef, and this is when the spirits from the otherworld, or Annwn, are said to come out to play. The Celts counted the days to begin on the evening before, not the morning off.

The same term is in the Cornish language called Kalan Gwav, or Allantide as it is mostly called now. In Breton language in modern day France it is called Kalan Goañv.

Wales, with its rich Celtic heritage, embraced these ancient beliefs, and Calan Gaeaf became a night filled with both celebration and fear. Fires were lit in villages to keep the malevolent spirits at bay, and families gathered indoors to share stories of ghosts and ghouls, all while keeping a wary eye on the night outside.

The Haunting Presence of Hwch Ddu Gwta

Among the many eerie figures associated with Calan Gaeaf, none is more feared than Hwch Ddu Gwta, a fearsome black sow with no tail. Legend says that Hwch Ddu Gwta roams the Welsh countryside on Calan Gaeaf, accompanied by a headless woman, the Y Ladi Wen, stalking those who dare to venture outside after sunset. Anyone unlucky enough to encounter this spectral beast would surely be doomed, dragged away into the darkness or even to the underworld itself.

To avoid Hwch Ddu Gwta and other restless spirits, people would rush home before nightfall, locking their doors tightly. The idea of being caught outside was a terror for many, as it was believed the spirits could claim anyone out in the open on this haunted night.

Hwch Ddu Gwta a Ladi Wen heb ddim pen
Hwch Ddu Gwta a gipio’r ola’
Hwch Ddu Gwta nos G’langaea
Lladron yn dwad tan weu sana.

The black sow and headless white lady,
Will try and catch the last to leave,
Thieves abound knitting stockings,
Beware the tail-less black sow on winter’s eve.

A game played by the bonfire was also that one of the men would wear a pig skin and chase the children to keep the fear and legend alive.

Divination and Dark Omens During Nos Galan Gaeaf

Aside from the lurking spirits, Calan Gaeaf is a night filled with ancient customs and rituals. One of the most unnerving traditions was a form of divination—an attempt to peer into the future and learn of one’s fate, particularly regarding death. People would gather around bonfires (coelcerth) and throw stones into the flames, each person marking their stone with a special symbol or name. After the fire had burned down, the stones were retrieved. It was said that anyone whose stone was missing in the morning would die before the next Calan Gaeaf. You could also see the people who would die if you ran around the church three times and peered into the keyhole of the church door.

Another dark tradition involved staring into a mirror at midnight on Calan Gaeaf, with the belief that the face of your future spouse—or, chillingly, a skull—would appear behind you. If you saw the skull, you would never marry, and die within a year.

Boys would cut ten leaves of ivy, throw one away and put the rest under the pillow. This would help them see the future, and if they touched the ivy, they would see witches, or gwrachod, as they slept. The men would also dress in women’s clothing mimicking the Gwrachod and go from door to door for treats. This was thought to repel the evil spirits.

The girls grew roses in hoops they could go through. They then cut the rose and put it under their pillows to see their future. Peeled apple skin was also thrown over the shoulders to spell the first letter of the future husband.

The Modern Halloween Celebration in Wales

Though today, many of these old customs have faded, the fear of spirits abroad on Calan Gaeaf still lingers in the corners of Welsh folklore. The old ways of celebrating seem like it’s being swallowed by the highly commercialized American Halloween.

On this eerie night, even the skeptics can’t help but feel a shiver down their spine as the wind howls through the hills and the night closes in. After all, as the old tales warn—if you’re out too late on Calan Gaeaf, you might just find yourself face-to-face with something that doesn’t belong in this world.

So when October 31st comes around in Wales, beware of wandering too far from home. Hwch Ddu Gwta might be watching, and the spirits may be closer than you think.
