The garden is named the serpent garden due to the topiary that snakes it’s way through this garden feature:
A topiary serpent in holly snakes through the watery Serpent Garden, revealing a different water sculpture hidden in each of its coils.
The water sculptures have been created by William Pye, one of the world’s leading water sculptors, who brings art and science together in his work. Each one is made from mirror-polished stainless steel.
The Vortex is one of seven water features that are part of the serpent garden. I do have a really good video of this which I will share with you later, I need to work out how to convert the file format so I can upload it to YouTube 
I will post some pictures of more of the water features in the next few days.

This is so interesting, C!
So if we build this water feature in Australia, do you think the vortex will go anticlockwise? Ha!
I am not sure… that means I have to go and visit to check it out
It’s an incredible place! When I look at the third photo, on Flickr large size, I have the feeling I’m slipping in. A bit dizzy… It will be nice to see the video. Thanks, Cherie.:)
I will work on the video. I think the software on my laptop may be able to do it… I can install it here because my programs drive is too full, I need to re-install everything!
Poison Garden, Serpent Garden – Cherie, you’re getting a bit dark here.
The poison garden came with a message… The serpent garden is actually quite fun and enlightening
I am intrigued. I look forward to seeing more of them
I don’t have all of them from this visit. When I have finished I will add some links to additional photos from a previous visit.

Some fascinating water features giving the place another dimension of variety for the visitors. Duchess genius !
Her insight is amazing. Hopefully the locals in Alnwick realise that now, I know they were struggling with it initially.
