The Evolution of Urban Planning, Infographic

I find it really annoying when people email infographics, asking me to post it for them. I consider them to basically be spam.

This one however was rather interesting, so I have decided to post it. It was sent to me from "Kon von der Schulenburg", who is an architect from an architectural firm called "Cantrell & Crowley Architects & Interior Designers". Their website is http://www.cantrellcrowley.com
