Pripyat, Ukraine

Pripyat, a city of nearly 50,000, was totally abandoned after the nearby Chernobyl nuclear disaster in 1986. Due to radiation, it has been left untouched ever since the incident and will be for many thousands of years into the future. Nature now rules the city in what resembles an apocalyptic movie.
