The Mystery of Harald Bluetooth’s Ring Fortresses
Harald Bluetooth’s ring fortresses are so unique, such impressive constructions, and such clear markers of a special period in prehistory that they have been recognized as part of our World Heritage.

But what exactly are they? What do we know? And how do we know it?

For nearly a hundred years, archaeologists have known about the existence of these fortresses and tried to understand them—their function, their builder, and the people who once lived there. Yet researchers are still far from agreeing, and new discoveries constantly shed light on Harald Bluetooth and the Jelling dynasty, challenging us to reconsider what we thought we knew.

Visit the Fyrkat fortress with one of our guides and gain new insights into why these fortresses still hold secrets for us.

The tour lasts approx. 30 minutes.

Meeting point: Fyrkat Mill Farm (Møllegården)
