Ever wondered why we keep laughing in the Netherlands every time the American's say we're the first nation to go under if the polar ice-caps melt? Well, this may be something for REALLY BIG THINGS or BUILD IT BIGGER. Officially started in 1950's, this is what they now want to have in New Orleans.
The last sections were added in 1997, making this one of the largest engineering features in the world which surround our whole nation and if wanted, we close ourselves off from the sea all together.

There are many sections surrounding the whole nation, starting in the north with "the closure dam" which was even constructed between 1927 and 1932 (see link below)

Then after the great flood in the 1950, they build one section after the other. But soon they realized that the nature had suffered severely from the lack of sault water if there was no proper exchange with the tides.

So they came up with another idea for the newer sections. A dam which can be closed whenever they want.
But with this there were problems unlike anything ever seen before.
"Darn, the sand keeps washing away" one person said. "Well, why don't we just put a carpet on the seafloor?" the other said (see link below)

and for this they needed a barge

On which they then later placed these pillars:

...building finally this (see link below)
A dam they can open and close whenever they want.

By now everything in the south was now closed. Only several harbours in the middle of the country weren't. This included the largest harbor in the world: Rotterdam. With literally hundreds of ships every single day and millions of tonnes of cargo, they could not build a dam in the river mouth like they did in the south. They decided to make doors which would span the whole width. Think of it as 2 eiffel towers on it's side.

The things you saw are some of the more impressive features of the literally dozens scattering the country. It's a real maze of constructions.

I hope you enjoyed the pictures and read and I hope someone from Discovery Channel will pick up on this for a show.

I've got my connections here as I'm a TV & Film maker from the industry.

...and guess who's building The Palm and the World Project in Dubai? Yes, correct, the Dutch
But I doubt it's actually bigger than the Delta Project, even though it's got hundreds of islands.
