Maemiseong Fortress (매미성)

Maemiseong Fortress is a wall that was built alone by citizen Baek Soon-sam to protect crops from natural disasters, who lost arable land to Typhoon Maemi in 2003. Repeatedly stacking square stones near the beach and filling them with cement has now become a castle reminiscent of medieval times in Europe. Its scale and design are so great that it is hard to believe that it was built without a single blueprint.
