Here is a short video by Dave Amos (of the YouTube channel City Beautiful) about the splitting of Berlin into two. What a fascinating urban case study. I just recently discovered his channel, but he seems to cover some interesting topics, all of which are related to cities and city planning. When Dave is not making YouTube videos, he is a professor of city and regional planning at Cal Poly. He also graduated with a Master of Architecture at some point before getting his Ph.D., so presumably he knows a few things about buildings and cities. I guess that also makes him an imposter architect, like me.
