Archaeologists in Denmark have discovered a structure that may have a "strong connection" with Stonehenge.

The "once-in-a-lifetime find" was made by Sidsel Wåhlin and her team in Aars, North Jutland, Denmark.

The discovery comprises 45 wooden posts arranged in an oval. The oval's diameter is around 30 metres and is believed to have been built between 2600 and 1600 BC.

“It is an extraordinary find,” Wåhlin, the curator at Vesthimmerlands Museum, said.

Henges, round earthen enclosures made of stones or timber posts, are found across Britain and Ireland. However, the latest findings in Denmark suggest that henges may have spread there, too.

“They are ritual centres and sites that are connected with the worship of the sun and the agricultural ritual practices of the time,” Wåhlin said.

“In order to decide to make such a specific monument you have to understand what it means and how to plan it.”

Discussing what the discovery means for our understanding of the Neolithic period, the archaeologist said: "It shows us that they are sharing the same worldviews on large-scale areas on how to be farmers, how society connects with the supernatural.

"Building monuments on this scale, you need to understand why and how.

"If a British person from the time would have come to the site they would have known what they are doing in there."
