I’ve heard of Natur-Park Schöneberger Südgelände — an old rail yard converted into a park, of sorts, nearby to where I live, but I’ve never visited.
Until today.
It’s a nice park — a 1€ entry fee (exact change required – and pay because there are random inspections) is required. Once inside there’s a small café, a water tower (a landmark), lots of abandoned rail tracks, and graffiti.
The graffiti is sanction — a list of rules at the entrance gives lots of leeway, but not painting on Sundays.
Not as fancy as the other places you’ve been hanging out, but it looks like a relaxing place to be.
