Under communism, Albania was in a near perpetual state of paranoia, formally at war with neighboring Greece, and firmly under the control of dictator Enver Hoxha. Reflecting its leader's military mindset, the country constructed some 700,000 concrete bunkers — one for every four citizens — most of which still pepper the landscape today. Dutch photographer David Galjaard shows how the buildings are a constant reminder of the past in Concresco, an award-winning photo book. In an interview with Wired, Galjaard gives the story behind some of the book's most stunning images, and explains how much more there is to Albania than the little concrete domes.
