In my opinion, Stockholm's Tunnelbana stations are some of the most beautiful in the world. The entire network is promoted as the world's longest art gallery. The stations are all unique and most feature paintings, sculptures or murals. I recently visited Stockholm for a long weekend and spent most of my time underground…visiting and photographing my favorite stations.
This is Stadion near the Olympic Stadium. It was one of the city’s first cave-like stations that features the exposed bedrock. The artists, Åke Pallarp and Enno Hallek wanted to remind the people that there is a sky not too far above, so the entire ceiling is painted bright blue. In addition, the rainbow represents the colors of the Olympic rings and serves as a tribute to the Olympic games hosted by Sweden in 1912.
The person on the platform happened to stand perfectly still as I took this 3 second exposure of the train pulling in to the station.
