'Extraordinary' timber circle discovered in Denmark is roughly the same age as Stonehenge

Archaeologists in northern Denmark have discovered the remains of a large timber circle that is thousands of years old and has parallels to England's Stonehenge. This open-air structure was likely part of a larger "ritual landscape" used by prehistoric people of the Late Neolithic (New Stone Age) and Early Bronze Age (2600 to 1600 B.C.).

"This is an extraordinary find," Sidsel Wåhlin, curator at the Vesthimmerlands Museum and excavation co-leader, said in a statement. "The timber circle provides valuable insights into the ritual practices and social structures of this internationally connected prehistoric society."

The newly uncovered circle consists of 45 postholes spaced roughly 6.5 feet (2 meters) apart, according to the statement, for a diameter of about 100 feet (30 m). Although no wood remains standing, experts guess that large, upright timbers had been placed in the small holes.

Timber circles, or wood henges, are somewhat mysterious, as no records have been left to explain what they were used for. But these henges have been found across northwestern Europe, particularly in the British Isles, where butchered animal bones and domestic waste found at some sites suggest people engaged in rituals and feasted there.

Woodhenge, located a couple of miles from Stonehenge, is perhaps the best-known timber circle. It was constructed of six concentric ovals of posts around 2500 B.C., roughly the same time as Stonehenge and, like Stonehenge, is thought to align with the summer solstice.

"The timber circle is not only a significant archaeological discovery but also a window into the past, offering us a glimpse of the ceremonial and ritual activities of our ancestors," excavation manager Andreas Bo Nielsen said in the statement.

Archaeological excavation of the postholes has already begun, with a goal of better understanding the construction and use of the timber circle. Vesthimmerlands Museum plans to share details of the excavation and findings later this year.
