Netherlands Delta Works: One of the 7 Wonders of the Modern World (Travel Guide)

by Netherlands8 comments

When we visited Veere, a small city on the Walcheren Island of Zeeland in the Netherlands, we also took the chance to see the Delta Works—one of the Seven Wonders of the Modern World (together with the Zuiderzee Works)!

…So what’s the Delta and Zuiderzee works?

Well, for centuries, the Netherlands has been constantly plagued with the problem of flooding during storms and it’s because of how most of its land (near the coast) is below sea level and/or less than one meter above sea level. In order to put a stop to this, as well as to reclaim more land, they started two projects…

  1. Zuiderzee Works – a man-made system of dams, land reclamation, and drainage that turned the dangerous Zuiderzee, a shallow inlet of the North Sea, into the tame IJsselmeer, and created 1650 km² of additional land (that started in the 1920s)
  2. Delta Works – a series of construction projects (dams, sluices, locks, dykes, levees, storm surge barriers) in the southwestern part of the Netherlands that were built:
    • To shorten the Dutch coastline
    • To protect the area around Rhine-Meuse-Scheldt from the North Sea especially after the widespread fatalities and deaths that happened after the ‘North Sea Flood’ of 1953

There are a LOT of technicalities and engineering terms involved here but the bottom line is that these two projects are majestic and grand—there’s a reason why they garnered a spot in the wonders of the world. But I guess, to really give you an idea about how impressive these ‘works’ are, I’ll let the photos below speak for themselves!

The Delta and Zuiderzee Works are located in various parts of the Netherlands; we obviously didn’t have the luxury of time to visit every spot, so we decided to check out one: the 9-km long Oosterscheldekering. Located between the islands Schouwen-Duiveland and Noord-Beveland, it is the largest of the 13 ambitious Delta Works series!

TRIVIA: The Oosterscheldekering is said to be the most difficult to build and the most expensive series of the Delta works. Apparently, they worked on this for more than a decade! (1976 to 1986)

You can choose to stop and park nearby to see more of the Oosterscheldekering up close, but you can also choose to just continue driving through the length of the highway.

Barriers Oosterscheldekering

But of course, we chose to stop by! My friend’s dad wanted us to see the barriers up close and of course, how could I say no to that?

We parked somewhere near Neeltje-Jans, an artificial island at one end that’s also used as an education center and a base for maintenance works. (This is the section on the bottom-right of the top-most image of this post. It’s totally free to park here and also free to get in on one of the nearby barriers.)

“Here the tide is ruled by the wind, the moon and we (the Dutch)”

Below is the view from the parking lot:

TRIVIA: The Oosterscheldekering is sometimes referred to by the Dutch people as an eight wonder of the world (apart from how the whole of it, the Delta Works, as one of the seven wonders of the world.

We proceeded to walk up to the highway to get into one of the barriers… as we were walking up the path, I was already in awe. Sure they were old, but they were HUGE! My friend’s dad is an engineer so he launched into a short ‘tour guide’ spree as he gave us more information about these storm surge barriers (the other information I acquired below are from sources online and the education center).

  • The dam is designed to last more than 200 years
  • The pillars are 35 and 38.75 meters high, weighing around 18,000 tons
  • The water levels must be at least 3 meters above regular sea level or else they will close the dam
  • The gates/doors/shutters of the barriers take one hour to close
  • The dam has been closed 25 times since 1986
  • The cost of operation costs $17 million a year!

TRIVIA: The photo above shows a marker or line on a pillar of a barrier, showing how high the sea level was during the North Sea storm/flooding of 1953.

TIP: If you want to see another Delta Work, I suggest going to Maeslantkering.

It’s a beauty! Located at Hoek van Holland and the river Scheur, it is said to be one of the largest moving structures on Earth (rivaling the Green Bank Telescope in the USA and the Bagger 288 excavator in Germany) and the only storm surge barrier in the world that has large movable parts. As you can see below, it’s a set of two swinging ‘doors’ that are almost as long as the Eiffel Tower.

To add more ‘wonder’ into this structure, it functions automatically! A computer is connected to these barriers so whenever a storm surge is expected, the doors would float towards one another in order to close the waterway. They are then ‘flooded’ and this additional weight will make them sink; thereby turning them into a barrier.

Booking Essentials

Book an AirBnB

TIP: It’s a good idea to crosscheck the prices with other popular travel insurance providers like World Nomads and HeyMondo (as my reader, you get 5% off)!
However, take note a travel insurance’s affordability typically means lesser coverage; so please always ensure that you read the fine print in order to decipher which travel insurance company is the right fit for you and your trip!

This was a really GREAT experience! It clearly shows how us, humans, have very astonishing abilities that we could come up with such amazing feats!

After seeing this, you bet that I am now on a mission of seeing the other 6 wonders of the modern world, namely: Channel Tunnel (between UK and France), CN Tower (Ontario – Canada), Empire State Building (New York), Golden Gate Bridge (California), Itaipu Dam (between Brazil and Paraguay), and Panama Canal.

    What a majestic feat of engineering! It’s such a shame the Philippines is too corrupted to ever come up with something like this… we need it!

    • Aileen

      I agree with you! Though we don’t have problems of flooding from the sea, we have problems of flooding from trash and poor waterway systems.

  2. Badet

    Wow! They built this for a purpose and now, it’s also a tourist attraction. They really have good urban planning since 1976! How I wish people here in the Philippine government can come up with something like that, and for long term use.

    • Aileen

      I wish the same too! This is such a majestic feat that helps stop flooding and we both know how Manila needs help from that (though of course our flooding is from trash, not from the sea so yeah; but still! It’s a problem that needs to be addressed)

  3. Blair Villanueva

    Wow! This is amazing! If only our government is not so corrupt, we can also afford to build this kind of structure that will help us to stand more stronger to flood problems and other related disaster.

    • Aileen

      Indeed; but I guess our officials have other priorities which is of course themselves :/

  4. Louisa

    It’s an amazing structure and I didn’t know it was one of the newest 7 wonders!

    • Aileen

      IT really was amazing! :D
