This German Town Carefully Reconstructed a 5,500-Year-Old Megalithic Monument After years of excavation and study, archaeologists have restored the Küsterberg burial site to its original layout to celebrate the annual European Day of Megalithic Culture Volunteers and archaeologists rebuilt the tomb site, lifting massive stones with modern excavation tools. Saxony-Anhalt State Office for Monument Preservation and Archaeology / Barbara Fritsch The Haldensleben forest in the German state of Saxony-Anhalt is home to more than 80 megalithic tombs from the Neolithic period—the largest concentration of such structures in central Europe. While some remain in fair condition, others have fallen victim to hazards ranging from ancient invasions to modern development. But instead of awaiting further decay, the town of Haldensleben has rebuilt a prominent 5,500-year-old tomb site known as Küsterberg to celebrate the European Day of Megalithic Culture, an annual holiday on the last Sunday of April. Archaeologists first excavated Küsterberg, located in a field southeast of Haldensleben, between 2010 and 2013, according to a statement from the Saxony-Anhalt State Office for Monument Preservation and Archaeology. Based on their findings, they were able to create a detailed plan of the site’s original layout. The semicircular site includes layers of rings around a central burial chamber, which is oriented from east to west.

In late April, the team unveiled the site, which has been transformed into an approximation of its original Neolithic layout. Like many Neolithic burial sites, Küsterberg is oriented from east to west. Some scholars speculate that this practice was meant to link the path of the sun to the course of a human life, according to Artnet’s Richard Whiddington. With an opening on the southern side, the semi-circular interior burial chamber once measured nearly 40 feet long and about 6.5 feet wide. It featured 19 orthostats—upright stone slabs—with seven capstones on top. Neolithic masons filled the gaps between individual stones with shards of greywacke, a type of sandstone that also lined the chamber floor. The reconstruction was based on years of measurements and careful study of the site's original layout.

These gaps were also filled with greywacke. The complex was ringed by an earthen mound, which archaeologists suspect was built with dirt taken from a nearby hill. The reason for the abundance of burial sites in the region is the dense population that once lived in the forests, as Johannes Müller, an archaeologist at the University of Kiel, tells the German TV station MDR-Fernsehen. He adds that scholars have identified ten settlements nearby, and every family may have built their own gravesite. Barbara Fritsch, an archaeologist with the State Office for Monument Preservation and Archaeology, tells MDR-Fernsehen that the site was built around 3600 B.C.E., when migrants from northwestern Europe settled in the area.

Much later, agriculture and road construction caused additional damage to sites like Küsterberg throughout central Europe. Last year, archaeologists uncovered a Neolithic burial landscape, including burial mounds and cattle sacrifices, as they excavated the site of a proposed Intel semiconductor fabrication plant in Magdeburg, Germany, per Artnet. Now reconstructed and preserved, the Küsterberg site will join Megalithic Routes, a network of European archaeological sites from the Neolithic period, per a statement from the University of Kiel. Researchers hope it will “inspire visitors with enthusiasm for the region and its long history.” Get the latest stories in your inbox every weekday.
