These eerie and beautifully shaped monuments (apparently called “Spomenik”) were built in the late 1960s in Yugoslavia honoring World War II. Belgian photographer Jan Kempenaers began documenting these fascinating Spomeniks images (which remind me of something strait out of H.G. Wells or some mid-century science-fiction novel) and eventually compiled them into a book. While once well traveled destinations these unique shrines to the past have fallen between the pages of history and are now deteriorating thanks to time, nature and vandalism. Take a look while we still have them.
