Delta Works (Netherlands)
Constructed in several different phases between 1950 and 2010, the Delta Works is a ongoing project that contains a compilation of dams, sluices, locks, dikes, levees, and storm surge barriers that act to protect the coastline of the Netherlands by reducing the amount that is exposed to open seas. It is also on the list of the Seven Wonders of the Modern World as composed by the American Society of Civil Engineers.
