Today, it is hard to believe that North and South Korea were ever a united land.
The repressive northern state and its wealthy southern neighbor look like different universes in German photographer Dieter Leistner's powerful photography project Korea-Korea. Their division in the aftermath of World War II and the subsequent Korean war wrenched families apart and set the nations on vastly divergent political and economic paths.
Leistner photographed public spaces in the North Korean capital of Pyongyang in 2006, and found similar locations in South Korea's capital Seoul in 2012. From commuters on public transport to students in class, his striking juxtaposition of everyday locations shows just how stark the divide has become.
