Welcome to Stratum 0 in Braunschweig, Germany!
We had a bit of trouble finding this place — it’s around the side of a fairly large building that was once a piano factory. The main door was ajar, and it was pitch black inside. Do we enter? Do we call? We walked in a bit, and were met with more darkness. A bit too spooky for our tastes. Our wits got the better of us and we decided to call and make sure we had the right place and not the lair of some homicidal maniac… It turns out if you just ring the doorbell the lights come on. Whoops.
Up to the top floor we go!
