I’d forgive you if you assumed all the stations looked the same, but that couldn’t be further from the truth. In reality, each U-Bahn station is unique and reflects the culture of the neighborhood it lives in. For instance, you might find murals of animals at the zoo station, and historical photos or street maps are also very common for older neighborhoods. I’ve attached some interesting ones, but the Rathaus Shoneberg station, which is built in a pond, is my absolute favorite! People come by and sit in the windows of the station, which makes me feel that the transportation is really well integrated into the culture of the city. In other words, U-Bahn stations have become meeting places, little food courts, and places to do work. They're not just for transportation!
