This sculpture is something new at the Desert Botanical Garden. It was created by Phoenix artist Patricia Sannit and is inspired by Citadel Erbil in Iraq. Ms. Sannit said she was inspired by the layering of time and history on top of each other over the centuries. It is composed of handmade bricks made the traditional way.
It inspired me to do some internet exploring of Citadel Erbil to see what it looks like for real.
I found these two small photos on the internet. What an amazing site still populated and growing. Check it out if you are interested.
