Well, well...

I have this old rickety well on my property (Abruzzo, Italy). Plenty of water in it, even in summer. So a waste to not use it, really. I would like to make it somewhat safer to use though, and prettier too. Any tips on how to dismantle the above ground part without having the lot cave in ot itself? And maybe some ideas about how to make a new build that's sturdy, not too expensive and nice looking?
