I can’t remember how I found Westenbury Mill Water Gardens, but I’m really glad I did. It’s an incredible place—honestly, possibly my favourite garden I’ve ever visited.
It’s essentially based around an old mill. The streams that once fed the mill have been used to create a water garden. The owner took those small streams and turned the whole area into this extraordinary landscape.
When you arrive, the garden is divided into different zones. There’s a huge pond they’ve built, a cairn garden, and a wildflower meadow at the far end. There’s even a sort of Monet-style bridge.
And then there are the follies, which are absolutely brilliant. There’s a stone water tower that works almost like a clock, with an incredible mechanism that draws the water up. Then there’s the glass bottle dome—completely random but very cool, literally a dome made out of glass bottles.
But by far the most amazing feature is the giant cuckoo clock. The whole thing was built by someone who is essentially a water engineer, and they believe it’s the world’s largest water-powered cuckoo clock. I happened to arrive at the perfect moment—the guy who currently maintains it was there explaining how it works. The mechanism is incredibly intricate, moving water up and down through pulleys, levers, pistons, and so on. And yes, it actually does a cuckoo at the right time—we saw it.
It’s not just a novelty, either—the whole thing is driven entirely by water pressure and gravity, with no electricity involved. The mechanism powers moving figures, gears, and the cuckoo itself, all through a network of channels, pistons, and counterweights. It took years to design and build, and it’s become a bit of a cult attraction among engineers and garden visitors alike.
It’s a fabulous garden. You absolutely have to go.
