How South Korea Built a 33 KM Wall to Reclaim Land From the Sea

South Korea built one of the most ambitious coastal engineering projects in the world — the massive *Saemangeum Seawall*, stretching approximately 33.9 kilometers across the coast. But why did South Korea build such a huge seawall? How did engineers construct it against powerful tides, and how did they use it to reclaim land from the sea? In this documentary, we explore the story of the *Saemangeum Land Reclamation Project* — from its beginning in 1991 to the completion of the seawall and the development of the reclaimed area. We look at the engineering challenges, construction process, land reclamation, infrastructure development, environmental concerns, and the controversy surrounding the destruction and transformation of tidal-flat ecosystems. The Saemangeum project has continued to evolve beyond its original agricultural purpose, with plans involving industry, infrastructure, tourism and other development. Official Korean government sources describe the seawall as approximately 33.9 km long and the wider project as a major state-supported land reclamation development.
