Art installation in Chatham shock!

The reason my nephew is in the vicinity is that he is working with the people who are building this just outside Chatham library, and their workshop is not very far from here.
I was delighted to see their work in progress from my office across the river and am bemused that it's located on the very same spot where once stood this.
It tickled me to send a message to my brother to notify him that I was watching his son's erection in my lunch-break.
