Note from Rocco Serrato:
It can’t be Yongsan because the walls are too short and without barbed wire. The bell bottom pants are vintage 70’s, but the few people in the pic makes me think this is not iSeoul but maybe nearer to the coast facing north monitoring the DMZ, is my best guess.
The Yongsan Legacy project proposes to capture the historical and cultural legacy of the site and to offer a unique experience for the park visitors in the future.
