B IG PI C T U R E Rådhuset Metro Station, Stockholm, Sweden With the Swedish capital being so compact and walkable, many visitors never get the chance to discover Stockholm’s remarkable metro system. From the 1950s, in an effort to bring art to the people, the government started hiring architects, painters and sculptors to develop the underground infrastructure, leading to the creation of perhaps the world’s most unusual art gallery. One of the artists was Sigvard Olsson, who had the idea to leave much of the bedrock around Rådhuset station exposed. I was immediately struck by the station’s grandeur so set up my camera and waited patiently for a clear scene. In an increasingly homogenised world, it’s wonderful to know there are places like this hiding just below one’s feet. BEN PIPE • PHOTOGRAPHER
