Bronze Age burial mound

From burial mounds in Malensbosch (part of the Vijlen forest) it can be deduced that the area was populated long before the Roman period. These round hills in the forest date from the band ceramics (Bronze Age) and are probably between 3500 and 5000 years old. Most of these burial mounds were excavated by the German geologist Liese in the 1920s and 1930s, but some are still untouched. This is the largest lonely burial mound along which a walkway was created. One of the most famous burial mounds in Malensbos, the “Kindergraf” (opposite Brasserie Lodge 7 in the bend of Epenerbaan), is open on one side and now has a sign. The grave owes its name to the milk teeth found in the remains of the burns. However, there were no other valuable assets. Given that some Roman shards have been found, experts believe that the tomb was looted by the Romans.
