With the global population surpassing 7 billion you might think there are no uninhabited places left on earth but you would be wrong.
From the snowy fjords of Scandinavia to the steamy jungles of South- East Asia, villages, towns and entire cities have been abandoned - sometimes overnight- never to be lived in again.
In this series we travel to the far corners of the earth, exploring the ghost town phenomena. Are any of the ghost towns being revived or will they forever remain monuments to a dark and mysterious past? Which towns of today could be the ghost towns of tomorrow? We speak to experts to get the facts and to locals to get a sense of the mystery.
