Incheon’s lost maritime history is recovered by recreating an inland sea around the historical Ahamdo island: allowing it to be an island once again. This sea will incorporate artificial reefs to shelter a delicate wetland ecosystem with an urban wilderness park running through it. Recreation areas, visitor’s center, and a floating pontoon pedestrian bridge reminiscent of the historical path to Ahamdo are integrated in ways that allow damaged ecosystem to regenerate while simultaneously drawing visitors to witness the gradual change. The landscapes are specifically designed to stabilize and regenerate the marsh while filtering polluting runoff from the adjacent urbanized areas. Thousands of abandoned boating vessels are re-used to create artificial reefs that control tidal flow allowing the re-creation of the tidal marsh to support local plants and wildlife. The new pedestrian bridge also doubles as an oyster habitat to filter and replenish the pollutants in the water.
