Borremose Fortress

Borremose Fortress is located approximately 3.5 kilometres southeast of Aars and is considered Denmark’s oldest known refuge fortress. The area is known to have been inhabited as early as around 250 BC.

The fortress was rediscovered in 1929, when a farmer working in the bog uncovered a thick layer of stones. It turned out to be a stone-paved road which, during the Iron Age, led through the bog to the raised area where the fortress was located.

Borremose Fortress covers an area of almost 1 hectare. Today, parts of the site have been reconstructed, giving visitors an impression of what the fortified village may have looked like. Of the two original ramparts, only the inner one has been preserved.

Archaeological studies show that the site functioned as a refuge fortress from around 300 to 150 BC. It was then abandoned for approximately 50 years – during the same period in which the Cimbri migrated. Around 100 BC, a village was established on the site, protected by sharpened oak stakes.

Today, Borremose Fortress offers a fascinating insight into Iron Age life, defence and settlement in Himmerland.
