Recently, the Chinese government opened access to the ghost town ‘404’, built to create the atomic bomb and for nuclear testing. The city was built back in 1958, and it is not on any map.
In the 1990s the city’s population was about one million people, many of whom were nuclear experts involved in the work of the Chinese nuclear bomb. In 1964, in the city blew up the first Chinese atomic bomb.
Now the city is home to about a thousand people.
