I love exploring the subway system of any city, but I find Berlin's public transport system to be especially interesting. Here's a look at the Friedrichstrasse station back in 1900. This station has seen alot, it was used by both the East and the West before German reunification. I hear that there were lots of twists and turns in the station at that time and you could easily find yourself at a dead end (on the West side at least). I recently took a tour to learn a bit more about Berlin's underground. I'll share some more shots and stories with you as the week goes on. Until then, you can see more murals at Monday Mural.
