Hey Chica - the poles are there to help stop the tree collapsing under its own weight. If you were nearly a thousand years old, you'd probably need a bit of support too!

I have seen a photo where all the poles and cables have been Photoshopped out, and I did consider doing that here, but some sort of supports have been in place for the last 100 years so I think they're becoming an integral part of the tree.
