Today's Photo of the Day treads the fortified Demilitarized Zone (DMZ) in Paju, South Korea. It was established by the Korean Armistice Agreement as a buffer zone between the Democratic People's Republic of Korea (North Korea) and the Republic of Korea (South Korea). The DMZ is 250 kilometres long, and about 4 kilometres wide.
Inside the DMZ near the western coast of the peninsula is Panmunjom, home to the Joint Security Area (JSA) and a meeting point between the two nations where negotiations take place.
The North Korean side of the DMZ primarily defends the country from invading South Korean troops. However, it also serves a similar function to the Berlin Wall—the DMZ stops North Korean citizens from defecting to South Korea.
On April 27, 2018, South Korean President Moon Jae-in and North Korean leader Kim Jong-un will hold their first meeting in the JSA before the summit between Kim and the current U.S. president, Donald Trump.
