When we were in London this past Summer, we visited the Tower of London, which I have been to on two previous visits to England, but never tire of. It is absolutely amazing, and I think probably one of the best things to do if you plan to visit London.
Anyhow, one of the most unusual things that I saw while we were there, and I am not sure how this relates to the Tower itself...but there were these very interesting monkey sculptures!
They are made out of what appears to be chicken wire, and perched up on one of the walls. I thought they were quite amusing!
