In the world of ancient history, this is pretty big news, reported by the Independent:
Stonehenge had a previously unknown wooden “twin” just 900m to its north-west, according to remarkable new archaeological investigations.
Using the ground-penetrating equivalent of an X-ray, scientists have discovered what appears to have been a circle of massive timber obelisks, constructed more than 4,200 years ago.
The newly discovered “henge” would have been visible from Stonehenge itself – and seems to have been part of a wider prehistoric ritual and religious landscape. Roughly 25m in diameter, it was almost the same size as the central part (the circle of standing stones) at Stonehenge itself.
The newly discovered monument – almost certainly some sort of Neolithic temple – is thought to have consisted of 24 wooden obelisks, each around 75cm in diameter and therefore potentially up to 8m high. The circle of obelisks was enclosed by an inner ditch and probable outer bank.
Of potential significance is the fact that the newly found henge “mirrors” a similar monument (this time long known to archaeologists) on the other side of Stonehenge – 1,300m south-east of the famous monument. Like the newly discovered site, it is in direct line of sight of Stonehenge and had two entrances. All three monuments would have been roughly aligned.
The discovery of the site north-west of the stone circle suggests that the Stonehenge landscape was even more complex than people have thought – and archaeologists are now keen to find further unknown elements of it…
