Trehøje

Trehøje is an archaeological site with three Bronze Age burial mounds in Mols Bjerge National Park, Denmark. The mounds reach 127 meters above sea level and offer views of Jutland's east coast and the islands of Samsø, Tunø, and Hjelm.

These burial mounds were built during the Bronze Age, when Denmark had a dense network of such burial sites. The construction of these elaborate structures shows the organized society and craftsmanship of that era.

The curved fields surrounding the mounds show medieval farming techniques where furrows were directed toward field centers to improve water drainage. These practices shaped the landscape for centuries and remain visible today in the distinctive plow patterns of the region.

Two marked hiking trails lead from the parking area: a 2-kilometer northern route and a 5-kilometer southern path. Visitors should wear sturdy shoes since the terrain is hilly and can be slippery in wet conditions.

Grazing animals maintain the nutrient-poor landscape around the mounds, creating conditions similar to post-ice age tundra. This process supports rare Danish insect species that are difficult to find elsewhere.
