Stockholm Cave Subway – by Alexander Dragunov

Not far from the Pionen cave office, a network of natural and man-made caverns snakes under the city streets of Stockholm. The Stockholm Cave Subway is quite possibly the most visually stunning subway system in the world, featuring painted caverns in rich colors that make daily travel a pleasure. Photographer Alexander Dragunov has spent plenty of time exploring and photographing the subway system of Stockholm, even compiling a full set of images into a book worthy of any modern coffee table. See it in his images if a visit isn’t on your bucket list.
