"Who owns the city" is a series I like from german organisation correctiv.org:
Who owns Hamburg?
https://correctiv.org/top-stories/2018/11/23/wem-gehoert-hamburg/
They crowdsourced Information on private property in different areas of the town and found interesting stories about speculation and gentrification. The series covers several cities. Really something special.
Many greetings and thank your for this course!
