There is a new, and maybe unfinished, piece of art near my office by Walnut Creek BART! You can see in the pictures below that it’s a very interesting structure comprised of multiple circles – some of which have openings among them.
There isn’t really any information online and no plaque at the structure itself, so I do wonder what the origin of this piece is? I want to know if it was designed to look old and rustic, or if it’s just incomplete (or old, and I’d just never noticed it before!). Does anyone know?
