Still standing strong!
The Delta Works, the flood defense system. The Delta Works have been built for decades. The original plan for building the Delta Works included the works in Zeeland, the south of Zuid-Holland and Noord-Brabant. These Delta works, especially the Oosterscheldekering and the Maeslantkering, still attract a lot of international attention. The American Society of Civil Engineers has declared the Delta Works one of seven modern wonders of the world.
