Hamburg is a city explored by lots of photographers for its architecture that mixes old and new. Artists are also going underground to explore the metro stations with colorful architectural and geometric details. Ali Sahba is one of them. He created a picture series of one of the latest metro station built in the city, Überseequartier located in the Hafen City district. For one of his latest series he immortalized the station of Jungfernstieg, located in the center of the city. Ali Sahba captured the colorful tiles, doors and passages. When we contemplate this series, we have the impression to walk in a giant Rubik’s Cube.
