Making a mountain out of basically no hills

So some Dutch "semi-professional cyclist-cum-journalist" named Thijs Zonneveld wrote a column half-jokingly proposing that the Netherlands should build an artificial mountain.

Thing is, the idea has kind of caught on, and now, he actually wants to find a way to build a mountain between one and two kilometers tall, which would be higher than the Burj Khalifa skyscraper, currently the world's tallest man-made structure.

So far, there are only a few minor snags:

Zonneveld has yet to figure out exactly how the Dutch mountain would be designed and built, what materials would be used, where it would be located, and, crucially, how much it would cost. He declined to put even a rough price tag on it.

Well, sounds like you've got a great proposal there, and I'm sure dozens of serious contractors will be lining up to work on it.

By the way, did I mention that most of the country is just above sea level? Sounds like a fantastic place for a massive structure like that.
