West Sea Barrage History

1980 - An Idea is Born

In the 1980s North Korea was looking to build its economy and assert itself on the world stage.  

The Taedong (translation - great east) River is the lifeblood of Pyongyang and South Hamgyong Province.

Starting in the Rangrim mountains in the middle of the country, it runs through Pyongyang and empties into the sea 40km southwest of the capital near the special city of Nampo.

As with most rivers, it is wide, saline and tidal as it enters the sea, and these factors presented problems. 

The width of the river estuary limited trade and transport between North Hwanghae and South Pyongan provinces, whilst the salinity and tidal nature of the river impacted farming lands in the surrounding area, as well as shipping traffic up to the capital.

From this, the idea of the West Sea Barrage was born.  

1981 - Construction Begins

Constructing the West Sea Barrage employed 30000 soldiers and countless thousands more civilians.

Over the following 5 years, 280,000 tonnes of steel, 1,100,000 tonnes of cement and millions of cubic metres of gravel and sand were deposited in the sea-river in an epic war of man against nature.  


In 1986, the sea was finally tamed and the work completed.

Official figures put the cost of the work on the West Sea Barrage at $4bn. However, such estimates don’t translate accurately between centrally planned and free-market economies.  

The barrage was opened by the President Kim Il Sung on 24 June 1986.

West Sea Barrage has been a source of pride for North Koreans ever since.  


It is 8km long with 36 sluices which can be opened or lowered in the rainy season, plus 3 locks for shipping traffic and 3 fish ladders.  

It has seawater on one side and fresh water on the other and the top provides a vital road and rail connection between North Hwanghae and South Pyongan provinces.

You can find images of the West Sea Barrage onto banknotes, and it regularly forms the backdrop of TV news bulletins and karaoke videos.


Most visitors arrive from Nampo or Pyongyang (and therefore the north), although if you have spent the day in South Hwanghae you will approach from the other direction.  

Either way, you will drive a section of the barrage to get to the visitor centre on Pi Islet.  

The visitor centre is in a lighthouse which resembles an anchor and doubles as the monument to the West Sea Barrage construction.  

There is a small snack/ souvenir shop, toilet facilities, and coffee. The coffee is not Pyongyang barista quality, but you’re out in the country now and it’s decent enough to drink whilst watching the video.

Upon arrival, you will be sat down and shown a video of the construction of the barrage.  

Even if you are eager to get out and take photos, it is only ten minutes or so and worth viewing if only to understand the effort that went into constructing it and the pride that Koreans retain in it to today.

  • After viewing the video, head out for a look at the barrage itself, and ask your guides if it is possible to walk up to the viewing platform for an even better panoramic view.
  • If you have a decent camera/ tripod, this is a good time to get a long exposure shot.
  • Check with your guides on timing- the barrage is only open from the north at some times, the south at others.  
  • If you are coming from the south, the sea is to your left; from the north to your right.
