Archaeologists ring date ritual Bronze Age stone circle to same year as Norfolk's Seahenge

Two 4,000-year-old Bronze Age monuments were built in burial rites during the same year on a Norfolk Beach

Hidden on a North Norfolk coastal beach, an early Bronze Age stone circle has been dated to the same year as the famous Seahenge monument which once lay 100 metres west of its ritual burial site.

Never excavated and left exposed to sea and weather erosion, archaeologists have used tree ringing to pinpoint the spring or summer of 2049 BC as the date when the formation, which is thought to have held a coffin and later burial mound, was constructed.

It was made of two oak logs, laid flat and surrounded by an oval of oak posts interwoven with oak branches.

An arc of split oak timbers formed the eastern side of the monument, with an outer palisade of split oak timbers surrounding the other elements. Almost all of the elements have been lost or dislodged since 1999, prompting the project to rescue the vital dating information.

“Seahenge is thought to have been a free-standing timber circle, possibly to mark the death of an individual, acting as a cenotaph, symbolising death rather than a location for burial. If it was part of a burial mound, the second circle would have been the actual burial place," says David Robertson, the Historic Environment Officer for Norfolk County Council who ran the Holme II dating project.

“The reasons why the second circle was built are not clear, but it may have formed part of a burial mound.

“The two central logs may originally have supported a coffin. The oval of posts and woven branches could have hidden the coffin from view before a mound was added, with the outer palisade acting as a revetment for the base of the mound.

“As the timbers used in both timber circles were felled at the same time, the construction of the two monuments must have been directly linked.

Sections of seven timbers were originally recovered from the second circle in 2004 and 2013. Experts measured and compared them to tree ring sequences from Great Britain and northern Europe, drawing direct similarities to Bronze Age timbers, including those from Seahenge. [...] culture24.org.uk/
