The tubular, bright orange passageways are a unique feature of the Marienplatz U-Bahn station. Hundreds of thousands of people pass through this station every day, completely enveloped in orange as they board their trains.
Almost everyone, including me, uses the main entrance/exit escalators on the other end of the platform. One day, however, I decided to explore more of the station and discovered this less frequented entrance. It is tucked away in a corner and only accessed by a small elevator from the main square.
I find the shapes, lines and curves to be fantastic here, as well as the slight bend in the passageway. Perhaps most importantly, there is a color other than orange! The dark green tiles provide great contrast, allowing the bright tunnel to draw your eyes right into it.
It has become, by far, my favorite place to enter the orange.
