Drielandenpunt is the point where the Netherlands, Belgium, and Germany meet, so three-country meeting point.
It also references the highest point in the Netherlands which, as a land as flat as its traditional and delicious pannekoeken, is not saying much : 323 meters (about 1060 feet) above sea level.
There are approximately 176 international tripoints in the world.
There is only one international quadripoint. This is a spot in the middle of the Zambezi River, in southern Africa, where Namibia, Zambia, Zimbabwe, and Botswana all touch.
