Maglehøj
The mound rests on a large hill of clay till from the last ice age, shaped by wind erosion after the glaciation and, on a smaller scale, by gravel digging.

The mound rests on a large hill of clay till from the last ice age, shaped by wind erosion after the glaciation and, on a smaller scale, by gravel digging. It is distinctly domed, with a narrow footpath and two deeper tracks that all lead to the top. From the summit there is a panoramic view over Frederiksværk, Arrenæs and Arresø and towards Hillerød; to the south, in clear weather, the towers of Roskilde Cathedral can be seen. On top stands a pedestal, a brick block about 1.5 m high with a bronze plate on one side.
A few metres south-west of Maglehøj lies Lille Maglehøj, 20 m in diameter and 3.5 m high.

In the 1980s the burial mounds were cleared of trees and bushes, but they have since become overgrown again. In the winter and spring of 2009 Halsnæs Municipality and the Nature Agency for North Zealand began to make the mounds visible again. The vegetation is to be cut back every year to keep a low plant cover, so that the soil is not lost to rain and wind. Lille Maglehøj is also looked after from time to time by the municipality's technical department.

Denmark has a very large number of surviving barrows, protected by law since 1937. Many were raised in the Nordic Bronze Age, from about 1700 to 500 BCE.

About this kind of monument
Danish barrows (gravhøje)
Denmark has a very large number of surviving barrows, protected by law since 1937, and the Atlas draws most of its Danish mounds from the national register of monuments. The oldest belong to the Funnel Beaker culture of the fourth millennium BCE, whose long barrows and stone-chambered tombs are described in their own articles. The great majority of the round mounds are younger. Many were raised in the Nordic Bronze Age, from about 1700 to 500 BCE.
The Bronze Age barrows hold remarkable burials. In a number of them, oak coffins stayed sealed and waterlogged, so that wool clothing, hair and textiles survived; only the bones of the dead are gone. The Egtved Girl, a young woman buried beneath the mound Storehøj in a woollen blouse and corded skirt with a bronze belt plate, is the best-known case: tree rings in her oak coffin date the burial to the summer of 1370 BCE. Borum Eshøj gave similar finds from the fourteenth and thirteenth centuries BCE. Later in the Bronze Age cremation took over from inhumation, and the dead were buried in urns.
Mound-building did not stop with the Bronze Age: Danish round barrows were raised from the Neolithic to the Viking Age.
When visiting, look for flat tops where old diggers cut in, and for the hollows where kerb stones were once removed.

Est. 3500–500 BCEHow this date was established: Type comparisonTypical range for megalithic mounds in Denmark; this site has not been dated itself. Denmark has about 20,000 preserved tumuli with the oldest around 5,000 years old; the Neolithic examples are Nordic megalithic mounds (dysser) of c. 3500-2800 BC.Source for this date
