Overview
The tumuli on the Jammerdaalse Heide are a group of seven burial mounds in the nature reserve of the same name, in the municipality of Venlo, in the Netherlands. The description of the group places the barrows in the early Iron Age, whereas a typological estimate in the catalogue gives a wider range of 4000 to 2000 BCE.
All seven mounds are national monuments (rijksmonumenten).

DescriptionSources for this section
Sources for this section
Seen from the surrounding clay pits, the mounds now lie on a kind of plateau high above them. The original cemetery must have been larger than the seven surviving barrows.
The largest mound of the group is called the Generaalsheuvel. Its diameter is roughly twice that of the other mounds, it lies on the other side of the road, and it was surrounded by a wide ditch. Excavation showed that it had already been plundered in the past. It is presumed that an important person was buried there.

Archaeological investigation of the group yielded urns containing cremation remains, together with bronze bracelets and rings that had been affected by fire.

Round barrows are found across the Low Countries and France, and many were raised in the Late Neolithic and the Bronze Age. They are hemispherical mounds raised over a central burial, which may be an inhumation or a cremation placed in a vessel. In France and Belgium, tumuli of the Hallstatt period belong to the early Iron Age, from about 800 BCE. Barrows were often reused, and later graves were sometimes cut into the mound long after the first burial.
Tradition and region
About this kind of monument
Low Countries and French barrows
Round barrows are found across the Low Countries and France. Many were raised in the Late Neolithic and the Bronze Age. The Bell Beaker phenomenon of the late third millennium BCE brought a new burial rite to western Europe: individual burials, often under a tumulus and with weapons, in contrast to the collective, weaponless burials of the earlier Neolithic. The Dutch hunebedden, the megalithic tombs of the north, belong to the earlier tradition and are described in their own article.
Round barrows are hemispherical mounds raised over a central burial, which may be an inhumation or a cremation placed in a vessel. Barrows were often reused: later graves were cut into the mound, sometimes long after the first burial, and many attract satellite burials. In France and Belgium, tumuli of the Hallstatt period belong to the early Iron Age, from about 800 BCE; from phase B of the Hallstatt sequence, tumulus burial becomes common and cremation predominates.
Dating relies on pottery and metalwork, and on radiocarbon dating where a mound has been dug. Many have been ploughed down, so the Atlas map reflects where mounds survived and were recorded as much as where they were built.
When visiting, look for the surrounding ditch or kerb, and for a later disturbance at the centre where a later grave or an old digging has cut the mound.
