Photographer Johnny Joo explores abandoned structures overtaken by the natural surroundings that had originally been tamed to make space for them. Joo captures ferris wheels, cottages, malls, schools, armories, and thruways as they slip back into obscurity, covered in undergrowth, vines, and trees. Based in Cleveland, Ohio, the 27-year-old photographer has spent the last ten years traversing the country to explore abandoned spaces. In 2012, Joo started a blog, Architectural Afterlife, where he features his work and writes reflections on his explorations and the history of the all-but-forgotten locations. Joo has published three books of his photographs, and is currently working on a fourth book, which is available for pre-order. He also shares updates on Twitter, Facebook, and YouTube.
