Zechstein Source Tours

Welcome to what was once "central Pangaea", a huge highly salinated body of water, the Zechstein Sea. It is now an underground salt layer spanning the area that's currently the North Sea, Northern Europe stretching all the way to Poland. In the northern Netherlands this salt layer is at it's thickest and most available for extraction using solution mining technology and just water. We invite you to take a look back into our history and discover how magnesium can help us create a sustainable future of wellness.
