Hunebeds are ancient burial mounds found primarily in the Netherlands and northern Germany. They were constructed during the Neolithic period, around 5,000 years ago, using large stones called megaliths. These structures served as tombs for the deceased and often contained multiple burials. The construction of hunebeds involved arranging large boulders in a specific pattern, creating a chamber covered by earth. They are significant archaeological sites that provide insight into the burial practices and social structures of early European societies. Today, hunebeds are protected as cultural heritage sites and attract visitors interested in history and archaeology.
