Inside South Korea's Impossible Wall - How South Korea Built a Wall Across The Sea

#SouthKoreaSeawall, #Saemangeum, #StrikingStructures Picture two walls of ocean, closing in on each other, with a 2.7-kilometer gap of open water still between them — and a current so violent it's scouring 20-meter holes straight through the seabed beneath it. That's the moment South Korea had to survive to finish a 33.9-kilometer wall built straight across open ocean, in water where the tidal range could reach roughly seven meters, twice a day, every day, for nineteen years straight. The wall would eventually enclose roughly 400 square kilometers of tidal coast — roughly seven Manhattans worth of seabed that used to flood and drain twice a day. But the hardest part was never the length.
