What Travellers Say
Reviews Summary
Visitors acknowledge Nonnebakken's UNESCO status but are often disappointed by the lack of visible ruins, as the fortress lies entirely underground. While some appreciate the historical significance and the information provided, others feel it's not worth a special journey, especially if it involves significant travel costs.
"Don’t make a special journey to see this UNESCO site as there’s nothing to see! There is a plaque in the park, but nothing at all visible on the surface as it has been built over. Nice park, but not if you’ve paid £50 for return ticket over the Storebaeltbrø to see it."
Katy Heard
"I personally met several people who came here specifically to see one of the UNESCO sites, but this information stand is all they had to be content with ℹ️ The remains of the Viking Age fortifications are underground, and in the relief of the modern city, even hints of their existence are invisible to the average eye 🧐"
Yan Bakhmat
"The violence is not apparent. Without signage, I wouldn't know there was an ancient monument there."

In-depth insights and expert knowledge
Understanding Nonnebakken's Historical Context
The primary challenge for visitors is that the entire fortress structure lies buried beneath the modern city of Slagelse. This means that unlike other archaeological sites, there are no visible ramparts, walls, or buildings to explore on the surface. Instead, visitors encounter information plaques and markers that explain the historical significance and layout of the original fortress. This can lead to a disconnect between the historical importance and the tangible experience of visiting the site.
Despite the lack of visible remains, Nonnebakken offers a unique opportunity for reflection. Standing on the ground where a powerful Viking fortress once stood allows for a moment to connect with the past. It's a reminder that history often lies hidden, waiting to be uncovered and understood through archaeological research and historical interpretation.
