These repurposed bunkers will blow your mind

Decades after World War II and the Cold War, the world is agonizing over nuclear threats from North Korea.

The country recently tested its most powerful intercontinental ballistic missile to date, which leader Kim Jong Un claims can reach the United States. North Korea's foreign ministry also said on Wednesday that war on the Korean peninsula is "inevitable."

These warnings may be one reason why some people — from Tokyo to Australia to the US — are showing an interest in purchasing bunkers designed to preserve life in the event of a nuclear explosion.

Many 20th century bunkers have, however, been repurposed since nuclear threats seemed to have waned in recent decades. Architects have turned old bunkers into all sorts of creative spaces, including farms, nightclubs, and apartments.

Take a look at these transformations below:
