Teufelsberg

Marty is fascinated with imagining what our current surroundings were like during the war or even during divided Germany days.  He has watched several movies and several series that depict our region of Berlin from back during war times.  In his shows they even name the neighborhood we live in and nearby neighborhoods.  It's strange.  So when he stumbled upon the old spy listening station that is just a short bike ride from our house, he was thrilled. 
We took our bikes and headed out not knowing what to expect.  He didn't do any research on the place just knew where it was on a map and knew it was within biking range.   The way there was through wooded area on mountain bike trails.  We have city bikes and were not at all

 prepared.  But we did it.  We biked up to the top of the "mountain" 
The place is surrounded by fencing and barbed wire.  You can see in but couldn't get in.  We circled the place and came to a sign that said it was closed on Mondays and Tuesdays.  It just so happened to be a Tuesday, unfortunately, so we were left just staring at the bizarre place wondering what it was like on the inside.

The bike ride home was a bit more direct as we found a bike path and avoided most of the mountain bike trail.  With all the fall colors it made the bike ride and trek worth it even though we weren't able to enter.
