00:00Imagine living in a country where the greatest enemy isn't war, not an earthquake, but the sea
00:06itself. It sounds impossible, but this is the reality of the Netherlands. About one-third of
00:12the country lies below sea level, and millions of people live in areas that would be flooded
00:17if the defenses failed. Everything changed in 1953, when a combination of high tide and a
00:23powerful storm broke through the dikes in the southwestern part of the country. Water rushed
00:29into towns in the middle of the night, killing more than 1,800 people and leaving tens of
00:34thousands homeless. The Dutch realized that building higher dikes wasn't enough. They
00:39had to learn how to control the sea. That's how the Delta Works was born. A massive system
00:45of dikes, dams, locks, floodgates, and movable storm surge barriers, considered one of the
00:51greatest engineering projects in history. But building it was an enormous challenge. Because
00:57the seabed was made of unstable sand and mud, giant prefabricated concrete blocks were transported
01:03by special vessels and sunk with extreme precision to create foundations capable of supporting
01:09structures weighing thousands of tons. The biggest highlight is the Oosterscheldekering,
01:15a movable barrier made up of 65 massive concrete pillars and huge steel gates. Most of the time,
01:23they remain open to preserve the marine ecosystem. But when a storm threatens the coastline, they
01:28can be closed within a few hours, blocking the force of the ocean. It's as if the Netherlands
01:33can close off part of the sea whenever necessary. And the most impressive part, the entire system
01:40was designed to withstand storms with a probability of occurring only once every 10,000 years. Today,
01:47the Delta Works protects millions of people, vast agricultural areas, and some of the most important
01:53cities in the Netherlands. It's no coincidence that the Dutch often say, God created the world.
01:59But the Netherlands was built by the Dutch. If you were impressed by this engineering masterpiece,
