On April 26, 1986, reactor number four at the Chernobyl power plant exploded, leading to the worst nuclear disaster in history. Pripyat, the town outside Chernobyl that was supposed to be a model of the modern Soviet state, was home to 50,000 residents who had to evacuate, leaving their whole lives behind. The area within the 30-mile exclusion zone will be uninhabitable for the next 20,000 years.
Twenty years after the accident, Chernobyl started to take on a new life, with the area opening to tourism for the first time. Visitors can tour the ruins of Pripyat, which in a little more than a quarter century has been crumbled away, overtaken by nature and wildlife. There are also a number of abandoned villages within the exclusion zone, some of which are still inhabited, albeit illegally. And of course, there are the remains of the power plant itself.
