In Drenthe there are no mountains or rocks. But hunebedden are made of huge stones. Where did they come from..? The answer is: from Scandinavia. About 200,000 years ago, during an ice-period, most of northern Europe including our country was covered by a thick layer of ice. The big boulders of which the hunebedden are made of have been transported to The Netherlands by slow moving ice-glaciers. Even today, digging in Drenthe's soil, smaller and bigger stones emerge.
