For one man, the sandy shores of the North Coast have become something else entirely.
[00:05 - Bill]
That's all I use, this old curtain rail, but to make it luxurious, get yourself a rake as well. That's all you really need.
[00:14 - Narrator]
Since 2018, retired teacher Bill, his homemade tools, and this vast stretch of Cornish sand at Polzeath have become the canvas for a very unusual form of creativity.
[00:27 - Bill]
I started off by being a tour guide round here, but I realized what a bad tour guide I probably was. I just sort of thought I'd draw some circles on the beach one time, and somebody on my Facebook page said, "Wow, that's amazing!" That was the start of the rabbit hole I went down.
[00:48 - Narrator]
Since then, almost every day of the week, Bill, his curtain pole, and rake can be found creating enormous works of art in the sand.
[00:58 - Bill]
This is an incredible canvas because every time I come down, it's different and it's completely unique.
[01:05 - Narrator]
And this stretch of coastline isn't just a canvas, it's a landscape woven through his family history.
[01:13 - Bill]
We have photographs of my mother on the beach just down there in 1933 with my grandmother. Like many people here, it's a family thing, and you come year after year for your summer holidays. I've always been drawn here.
Connection to the surf and the sand... they say surfing is cutting shapes onto the waves, but I'm actually cutting shapes onto the sand.
[01:39 - Narrator]
But long before families came here for summer holidays, people were already being drawn to this stretch of coastline.
[01:48 - Bill]
Two, three thousand years ago, people were coming to this place to be buried because of the alignment and the way the sun set, and everything kind of aligns. When I'm on the beach, I'm very aware of how things line up.
[02:04 - Narrator]
Across Cornwall, prehistoric burial sites and ancient stone circles stand across the cliffs and headlands. Many carefully positioned to align with the movement of the sun.
[02:17 - Bill]
Sun's up there and then it will be going down over there. At the summer solstice, it goes down over there somewhere, and that sort of aligns with this whole idea of: that's where the sun goes down, that's where the end of the earth is, and they built their burial grounds here so that they could be on their way to the—whatever it was they were going to—the end of the world and the other life.
[02:41 - Narrator]
And the circles Bill draws in the sand are inspired by that same ancient fascination: finding patterns, meaning, and alignment in the landscape around him.
[02:54 - Bill]
What I'm thinking of is doing something in here, in this bit here, which then expands into that area. You don't have to think about it too much, and you don't have to worry about it too much. It's not something I have to work out, get a piece of paper out and work out. It's more that I'm thinking, Yeah, that just sort of fits and it flows. It's more like a flow state, it's more like a meditation.
It's good to be abstract. I don't want to draw something which someone's going to say, "That doesn't look like a horse! You're meant to be drawing a horse, that's wrong." And I used to do a piece, and I used to go up on the cliff, and then I realized I missed out a piece, and then I had to go all the way down again to correct my mistake, and it used to take ages. I don't bother now. I'm enjoying now just sort of messing around. It's not the Mona Lisa.
[03:52 - Narrator]
After almost a decade spent creating giant artworks, Bill still finds himself returning to the same beaches. Not for recognition or financial reward, but for the simple pleasure of being here.
[04:06 - Bill]
This is my gift to the beach and to people who may be walking around. It's just the enjoyment of just being involved in that on the beach.
And that's aligned exactly right! That's going straight over Stepper Point, and it's going over Trevose Point, and then it's going across Polzeath to the end of the world. Everything makes sense, doesn't it?
[04:33 - Narrator]
After a couple of hours, the eye-catching artwork is complete.
[04:43 - Bill]
You come out and you go, "Wow!" Even though you've seen it down there. I mean, if I drew that shape on a piece of paper, you'd look at it and think, Not very interesting. But you put it there, and because everything around it is very interesting, it kind of fits there really nicely, doesn't it? Yeah, quite happy with that. (laughs)
[05:00 - Narrator]
But like the tide itself, Bill's artwork is only ever temporary.
[05:06 - Bill]
Now half of it's gone, it's finished, really. It will be all gone in a few seconds, probably.
[05:17 - Narrator]
Coming up... at Watergate Bay, it's do-or-die as the Under-21 Surf Competition reaches the final.

For those of us who walk the rugged paths of the North Cornwall coast, Polzeath Beach is a familiar friend. But to watch it transform from a blank slate of wet sand into a sprawling, geometric masterpiece is to witness a unique kind of coastal magic.
A recent episode of Channel 5's Cornwall: A Year by the Sea cast a beautiful spotlight on New Polzeath’s own Bill Bartlett—retired teacher, local guide, and sand artist. The feature revealed not just how he creates his colossal sand mandalas, but the fascinating web of history, geometry, and local connection that binds the entire production together.
What made this broadcast so compelling was how the entire episode beautifully harmonized with the themes of Bill’s segment. The program was structured around our connection to the coastal landscape, its elements, and how we find rhythm within its natural boundaries.
Impermanence and the Tidal Shift: Bill’s serene acceptance that his hours of hard work will inevitably be swallowed by the incoming Atlantic tide perfectly mirrored the segment on the Under-21 Surf Championships at Watergate Bay. Surfers live at the mercy of the exact same ocean rhythms, chasing a fleeting "flow state" on waves that disappear the moment they are ridden.
Transforming and Aligning the Landscape: While Bill explored how prehistoric ancestors used coastal alignments to build sacred sites, the segment on beavers transforming the Cornish landscape showed nature’s own architects reshaping the terrain. Both stories highlight how life—human or wild—interacts with geography to establish patterns of flow and balance.
The Pull of Generations: The segment featuring a family campsite preparing for a busy summer echoed the deep generational ties of the coast. It directly mirrored Bill’s reflection on his own family roots, highlighted by a treasured photograph of his mother and grandmother on Felpham (not Polzeath) in the 60's.
If you’ve ever strolled down to the beach at low tide, you might have spotted Bill walking with purpose. He doesn't carry high-tech surveying equipment or GPS markers. Instead, his toolkit is wonderfully, charmingly simple:
An old curtain rail (or long wooden pole) to scribe his initial, perfect circles.
A simple garden rake to add texture, shading, and depth.
A marked length of rope based on the Fibonacci sequence—the mathematical sequence of the Golden Ratio found everywhere in nature.
As Bill joked on screen:
"That's all I use, is this old curtain rail, but to make it luxurious, get yourself a rake as well."
With these basic tools, Bill coaxes magnificent geometric figures like the Seed of Life from the beach. He aligns his drawings precisely with ancient landmarks and the path of the sun. Pointing out over the water, he noted:
"That's aligned exactly right! That's going straight over Stepper Point, and it's going over Trevose Point, and then it's going across Polzeath to the end of the world."
The incredible warmth and intimacy of Bill's segment didn't happen by accident. It was filmed on 18 May 2026—a spectacular spring day when the pink thrift was in full bloom across the Polzeath cliffs and the beach was beautifully quiet and empty of the summer crowds.
The production itself was a deeply neighborly affair, captured by a crew of familiar local faces:
Ruth & Rupert Binsley (Rock): The segment was shaped by producer Ruth, who is married to camera and drone operator Rupert Binsley. The couple lives just down the road in Rock. Having a drone pilot who lives on the estuary means understanding exactly how to capture the scale of the sand art from the air.
James Knott (Trebarwith): Serving as the director and producer was James Knott, based just up the coast in Trebarwith. James’s native eye for North Cornwall’s dramatic coastline, combined with the spectacular spring lighting, ensured every frame felt incredibly cinematic.
When the people making a television program are locals from Rock and Trebarwith, the dynamic on set completely changes. Bill wasn't talking to a crew of strangers; he was sharing his passion with people who walk the same paths and watch the same sunsets.
This deep-seated local trust is exactly why the interview felt so incredibly candid, warm, and meditative. Rupert's drone and James's cameras were allowed to linger, capturing the quiet majesty of a solitary artist on an empty beach with a reverence that only locals can bring to the screen.
The next time you are out on a Polzeath Walks route, keep your eyes on the beach below as you round the corner near New Polzeath. If the tide is low, you might just see a series of perfect, giant circles emerging from the sand—a beautiful, temporary gift to the beach from one of our own.
