A deep dive into Hen Galan and the Gwaun Valley
In a hidden valley in north Pembrokeshire, New Year’s Day falls on January 13th. It has done so for over 270 years, and nobody here sees any reason to change.
The Gwaun Valley is one of those places that makes you question whether time works the same way everywhere. The lanes are so narrow that two cars cannot pass. The woods are so ancient they feel Tolkien-esque. The local pub serves beer through a hatch in the wall from a jug, and the only option is Bass. And every January, while the rest of the world has long since taken down their decorations and returned to normal life, the 300 inhabitants of this valley gather to celebrate Hen Galan: the Old New Year.
This isn’t a quirky revival or a tourist attraction. It’s a living tradition that has continued unbroken since the rest of Britain moved on without them in 1752.
Here’s the story of how one Welsh valley got stuck in time, and why they’ve never wanted to leave.
The Calendar That Changed Everything
To understand Hen Galan, you need to understand what happened to calendars in the 18th century.
For over 1,600 years, Europe ran on the Julian calendar, named after Julius Caesar who introduced it in 45 BC. It was a decent system, but it had a flaw: the Julian year was about eleven minutes longer than the actual solar year. That doesn’t sound like much, but over centuries it adds up. By the 1500s, the calendar had drifted ten days out of sync with astronomical reality. Easter was sliding slowly towards summer.
Pope Gregory XIII fixed this in 1582 by introducing the Gregorian calendar, which corrected the drift and removed those extra minutes. Catholic countries adopted it immediately. Protestant countries, suspicious of anything coming from Rome, held out for decades or even centuries.
Britain finally made the switch in 1752. Parliament passed the Calendar (New Style) Act, and in September of that year, eleven days were simply deleted. Wednesday 2nd September was followed by Thursday 14th September. The country went to bed on one date and woke up on another.
People were not happy.
There were riots in some cities. People believed they had been robbed of eleven days of their lives. Landlords still demanded a full month’s rent for September. Workers wanted a full month’s wages. The phrase “Give us our eleven days” became a rallying cry for protests.
Most of Britain eventually accepted the change and moved on. But in certain remote communities, far from the centres of power and deeply attached to their traditions, people simply refused. They kept celebrating their festivals according to the old calendar, as they always had.
The Gwaun Valley was one of those places. And unlike almost everywhere else that resisted, they never stopped.
A Valley Carved by Ice – The Gwaun Valley
The Gwaun Valley isn’t just historically isolated. It’s geographically isolated too, and has been since long before humans arrived.
The valley was carved at the end of the last Ice Age, around 10,000 years ago, when vast quantities of meltwater from retreating glaciers cut a deep V-shaped channel through the Pembrokeshire landscape. Geologists consider it one of the most important meltwater channels from the last Ice Age anywhere in the British Isles.
The result is a ten-mile ribbon of steep-sided woodland running from the Preseli Hills down to the sea at Fishguard. The River Gwaun, which gives the valley its name, loops through the bottom, feeding tributaries that have carved their own narrow side-valleys into the slopes. The whole area is thick with sessile oak, beech, alder, and ash. Birdwatchers come for pied flycatchers, wood warblers, redstarts, and nuthatches.
The Rough Guide to Wales calls it “one of the great surprises of Pembrokeshire: a bucolic vale of impossibly narrow lanes, surrounded by the bleak shoulders of bare mountains.”
The surrounding Preseli Hills add another layer of ancient mystery. These are the source of the bluestones used to build Stonehenge’s inner circle, somehow transported 170 miles to Wiltshire around 4,500 years ago by methods that archaeologists still argue about. The hills are scattered with standing stones, burial cairns, and prehistoric monuments. One stone circle, Bedd Arthur, is named for the legend that King Arthur himself lies buried there.
This is a landscape where the past never quite lets go. Celebrating New Year on a different date than everyone else fits right in.
What Actually Happens on January 13th
Hen Galan begins in the morning with children.
Kids from the local primary school, Ysgol Llanychllwydog, get an unofficial day off to participate in the tradition. They walk from house to house through the valley, singing traditional Welsh songs and wishing the residents Blwyddyn Newydd Dda: Happy New Year. In return, they receive calennig, which translates as New Year’s gift but usually means money or sweets.
Liliwen McAllister, who grew up in the valley, described it to WalesOnline: “When I was young, me and my friends would walk around to the different farms to sing songs and receive gifts, and if you arrived at a home that was sitting down to eat, you’d have to join them at their table and enjoy the meal as well. These days parents drive their children to the different farms to sing.”
The tradition of calennig goes back centuries and was once common across Wales on New Year’s morning. Children would carry decorated apples stuck with three sticks and studded with cloves and evergreen, symbols of good luck for the coming year. The custom died out almost everywhere else but survives here in its original context.
As the day continues, the adults gather. Traditionally, Hen Galan was considered more significant than Christmas, and families would prepare a feast to match: turkey or goose, mince pies, plum pudding, trifle. Many still cook a full roast dinner for the occasion.
And then, inevitably, everyone ends up at the pub.
Bessie’s: A Pub Like No Other
The Dyffryn Arms in the village of Pontfaen has been in the same family since 1840. For most of that time, and certainly for living memory, it has been known simply as Bessie’s.
Bessie Davies ran the pub for over 70 years, becoming something of a legend in the process. She passed away in December 2023 at the age of 93, but her name remains above the door and the pub continues exactly as she left it, now run by her granddaughter Nerys.
Walking into Bessie’s is like walking into someone’s front room, because that’s exactly what it is. There’s no bar. There’s no food menu. There’s no television. You enter through a side door into a small parlour with well-worn tiles, bubbling wallpaper, and wooden furniture polished by decades of use. Beer is served through a hatch in the wall, poured from a jug straight from the barrel. The only ale available is Bass, and that’s not changing.
“I’ve got a selection of bottled beers but I stick with Bass,” Bessie once told a visitor. “You know what you’re getting with Bass.”
The pub survives on low overheads. It’s the family home. Lights are turned on when someone comes in. A log might be added to the fire if you’re lucky. Atlas Obscura describes it as “a fitting representation of the Gwaun Valley community, whose members, having lived in relative isolation for centuries, take pride in doing things their own way.”
On Hen Galan, the pub fills. People who’ve been walking between farms all day come in to decompress. Songs are sung. Stories are told. The new year is properly welcomed, thirteen days after the rest of the world has moved on.
Why It Survived Here
Other communities resisted the calendar change in 1752. Why did the tradition survive only in the Gwaun Valley?
Part of the answer is geography. The valley is genuinely isolated. The lanes are barely wide enough for a car and were designed for horses and carts. Before modern transport, reaching the outside world required significant effort. News and fashions arrived slowly. Change arrived even slower.
Part of the answer is language. The valley has remained predominantly Welsh-speaking throughout its history. When most children from the local school take the day off for Hen Galan, they’re continuing a tradition conducted entirely in Welsh. The songs are Welsh. The greetings are Welsh. The culture is Welsh. This isn’t a performance for visitors. It’s a community talking to itself in its own language.
Part of the answer is community size. With only around 300 inhabitants, everyone knows everyone. Traditions don’t survive in the abstract. They survive because actual people pass them to actual children, year after year. In a small community, there’s nowhere for a tradition to hide and die quietly. Either everyone does it or no one does.
And part of the answer is stubbornness. The Welsh have a long history of holding onto things the English would prefer they dropped. Celebrating New Year on the wrong date is, in its own quiet way, an act of resistance. It says: you can change the calendar, but you can’t change us.
The Mari Lwyd Comes to the Valley
Hen Galan isn’t the only old tradition that survives in the Gwaun Valley. The Mari Lwyd makes appearances too.
The Mari Lwyd is a horse’s skull mounted on a pole, draped with a white sheet and decorated with ribbons. A person hides beneath the sheet, operating the skull, which sometimes has a hinged jaw worked by strings. The Mari is led from house to house by a group of singers who request entry through song. The householders must reply with their own verses, and the exchange continues until one side runs out of rhymes. If the Mari wins, her party is invited inside for food and drink.
It sounds bizarre. It is bizarre. And it’s been happening in Wales for centuries, though it died out in most places during the 19th century when Methodist chapels objected to the drinking and rowdiness that accompanied the Mari’s visits.
In the Gwaun Valley, and at nearby Tafarn Sinc in the village of Rosebush, the tradition continues. The Mari appears between Christmas and Twelfth Night, and sometimes makes a special appearance for Hen Galan. The combination of a zombie horse and a calendar from 1752 makes the valley feel like it exists in a parallel timeline where certain things simply never ended.
Visiting Hen Galan
If you want to experience Hen Galan, you need to plan ahead.
The celebration happens on January 13th every year, which falls on a Monday in 2025 and a Tuesday in 2026. The valley is about a 30-minute drive from Fishguard, heading inland towards the Preseli Hills. The roads are narrow and winding, and if you’re not used to single-track lanes with passing places, take it slow.
The Dyffryn Arms (Bessie’s) is the obvious destination, but it’s small. If you’re going on Hen Galan itself, expect it to be busy. Arrive early, be patient, and understand that you’re a visitor to someone else’s tradition, not a customer at a tourist attraction.
Outside of Hen Galan, the valley is worth visiting any time of year. The walking is exceptional, with trails leading up onto the Preseli Hills and along the river. The landscape feels genuinely unspoiled, the kind of rural Wales that has largely disappeared elsewhere.
For accommodation, look at cottages in the surrounding area. Newport, at the foot of the Preseli Hills, has excellent options including Llys Meddyg, a boutique coaching inn with a serious restaurant. Fishguard has more choices and is close enough to drive in for the celebration.
If you want to see the Mari Lwyd as well, check the Facebook page for Tafarn Sinc in Rosebush, which hosts Mari Lwyd evenings throughout the winter season. The pub is itself worth a visit: a community-owned establishment in a converted railway building, full of character and good beer.
What It Means
There’s something almost subversive about Hen Galan. In a world that increasingly runs on global time, where everyone celebrates the same New Year at the same moment regardless of where they are, this one small valley in Wales has simply opted out.
It would be easy to dismiss it as nostalgia or eccentricity. But there’s something deeper happening here. The people of the Gwaun Valley aren’t pretending the calendar didn’t change. They know what date the rest of the world thinks it is. They’ve simply decided that the way they’ve always done things matters more than conforming to a system imposed from outside.
That’s a very Welsh attitude. It echoes through centuries of history, from the survival of the Welsh language against all odds to the continued existence of traditions that the industrial revolution and the modern world should have erased long ago.
January 13th isn’t a random date. It’s a statement. It says: we were here before your calendar, and we’ll be here after it. Time moves differently in the Gwaun Valley, and they like it that way.
Blwyddyn Newydd Dda, whenever you choose to celebrate it.
