The demilitarized zone between North and South Korea is the most heavily fortified border on earth.
But the south is planning to open a new eco-tourism site along its frontier with North Korea.
The buffer zone has been tightly restricted for more than 50 years creating an untouched nature reserve.
They hope to rebrand the area as a place of peace, not war.
