I have been casting an eye over this amazing piece of workmanship just outside Glyn on my way home for some time now.
Today I had the camera with me, and so, herewith some photographs.
This, in my opinion is an amazing piece of land art – functional, I know, beautifully crafted, man and nature combined, environmentally friendly, and it looks terrific. (A “found” object perhaps?) 
Would it not be fun to be able to transport a section of it to no 10 Downing Street……put it up outside the V and A….Tate Modern……….
It is a particularly well-laid hedge – we remarked on it when it was being laid, and Martin and Gaynor have also commented on it. There are definite aesthetics and styles in hedge-laying – there’s the old chap around Cefn Canol who has a very precise style, and there’s the DIY look to that stretch of winter hedging just by the telephone box in Rhiwlas. I don’t know of any landscape artists who lay hedges? I know Antony Gormley built walls – but did he ever lay hedges? It would be a very long-term art form. There’s that “outsider” artist in California who shaped trees – sort of like hedging.
And yes: if Whitehall is going to ram windfarms, electricity pylons and high speed rail lines through the countryside, let’s plant hedges along Downing Street!
Interesting John! I can think of many more country “things” that might also be usefully transferred to Whitehall!
(I’ve been rebuked for referring to it as layered, instead of laid – so I’ll know next time!)
