Miniatur Wunderland, an amazingly detailed, 1,300-square-meter miniature civilization built by a pair of German brothers, now boasts the world’s largest model railway and airport.

The miniature Wunderland has been under construction for the past six years, and includes eight different sections that give visitors a glimpse of mini-versions of Scandinavia, Germany, Austria, Switzerland, America, and more. With over 900 trains, 250 computer-controlled vehicles, and even airplanes and working miniature boats actively traveling across the teeny landscapes, the recreation is perhaps the most life-like model anywhere in the world.

Over one million visitors a year travel to Hamburg to awe at the bustling, ever-expanding world of tiny humans, animals, and scenery. Upon close inspection, one can spot carefully-constructed scenes such as a mini-Las Vegas strip, a group of archaeologists exploring a cave, a crime scene crawling with police figurines, a group of fitness gurus exercising in a pint-size gym, a UFO landing, and churchgoers entering a cathedral.

The number of hours it’s taken to build the incredible display (500,000 so far!) is constantly increasing as construction continues. The model’s creators, Frederick and Gerrit Braun, both 41, plan to add a mini-England, France, and Africa to the Miniatur Wunderland by 2020.
