They have to fence this off really. It will have cost a fortune to get the work done. They fenced off Le Refuge when they had the statue in the Bath Fountain restored last year, and that wouldn't have cost anywhere near as much as this. I believe there should be a way for people to get access to it, and even to go up it on some occasions, but to leave it freely open at all times to people in today's world is just asking for trouble.
Also, I think they've done a decent job and it looks loads better than it has for decades. I think I would have liked to see a bit of red colour too though. I really like the railings. I look forward to viewing it in person
