A mining pit between Gransee-Kraatz and Zehdenick-Osterne.
Although it looked like the border of a field on the aerials, it was clearly inside the mine, which probably had been extended since the pics were taken. Climbing down there was not an option.
Report will be done later
Train traffic irregularily. Please use the tram.
500 m from the hash. No way through here.
Welcome to Osterne. Wtf is Osterne?
Got as close as 100m (and forgot to take a picture at that point)
The hash is down there, somewhere
More modern ruins. The large living blocks are abandoned as well
by bike: long distance trail Berlin-Copenhagen. Starts at the station. Length of way: 6 km. Hu. I always believed it was more than 6 km from Berlin to Copenhagen.
