Kong Asgers Høj is Denmark's largest passage grave, located on the island of Mon and dating to the Neolithic Funnel Beaker culture around 3000 BC. The megalithic structure consists of a burial chamber 10 meters long and 2 meters wide, accessed through a narrow passage approximately 10 meters in length. Built from boulders weighing up to four tonnes each, the grave functioned as a communal burial site that was repeatedly opened for new interments and later reused for Corded Ware culture burials. Archaeological investigation began in 1839 when merchant Gustav Hage attempted to find treasure within.
