NHER 33771 (Monument record) - 'Seahenge' Early Bronze Age timber circle on Holme Beach

August 1998.
Timber circle surrounding tree stump in submerged forest discovered by [1].
Middle Bronze Age palstave within 15m (50 feet) of circle (now recorded under NHER 38041).
Site visited by E. Rose (NLA) with finder [1].
See brief report with plan (S1) and photographs (S2).
See also a brief report acompanied by correspondence (S17) and other internal correspondence (S64).

Autumn 1998. Evaluation excavation.
Six samples from five timbers submitted for dendrochronological dating. The resultant chronology could not be dated by dendronchronological means and high precision radiocarbon dating was carried out on six samples from the tree stump.
See initial short published notes (S3), (S4), and more fully (S5).

Full publication alongside of the results of the subsequent excavation in Norfolk Archaeology (S7).
Photographs (S8) and slides (S9) from the evaluation are held by the Norfolk Historic Environment Record.

May to August 1999. Excavation.
The structure was perceived to be under threat from damage and erosion from the sea - as such it was fully excavated. This involved the removal of the timbers, a programme of stratigraphic recording and environmental sampling.
The structure comprised a elliptical circumference of fifty five large oak posts and one smaller upright timber, set around an inverted oak tree. Maximum diameter of 6.78m, with the tree set slightly southwest of the centre.
The central tree had two holes cut through the trunk on opposite sides, with a length of honeysuckle rope passed through the holes and tied in a knot.
A maximum of twenty five trees were used to build the structure. Evidence of woodworking was recovered, including felling, trimming, splitting and flattening. 422 pieces of wood debris were found, including woodchips. Toolmarks recorded from a total of fifty nine possible tools; the maximum number of tools used is probably nearer 51. The toolmarks are probably the largest assemblage of Early Bronze Age toolmarks yet recorded in Britain.
The structure was built at a single point in time. Dendrochronological dating of fifty five samples revealed that the timber circle was constructed in the spring or early summer of 2049 BC, during the Early Bronze Age.
Environmental analysis demonstrated that the structure was built on a saltmarsh. During the Bronze Age freshwater reedswamp and alder carr spread over the saltmarsh and the monument itself.
Two timbers (context 35-37 and 65) may have been the first timbers set in place. These were placed on a southwest to northeast alignment, on the approximate direction of the midsummer rising sun and midwinter setting sun. This may have been deliberate or unintentional.
All but one of the circumference timbers were placed with their bark facing outwards. The timber with the split face facing outwards must have had significance.
The structure has been interpreted in various ways. These include a monument to mark the death of an individual, the death of a tree or the regenerative failure of trees and the commeration of an event, a life or the culmination of a celebration or festival.
See published article (S3) for further information. The results of this work are also summarised in (S17).
The fragmentary remains of the timber circle are now in the King's Lynn Museum (KILLM : 2007.1100). The excavation archive has been deposited with the Norwich Castle Museum (NWHCM : 2017.484).

August 2002. Norfolk NMP.
The site of a Bronze Age timber circle with central inverted tree stump which is located within the intertidal zone on Holme beach and is visible on oblique aerial photographs aerial photographs taken in 1999-2000 ((S54)-(S58)). The timber circle itself did not appear to be visible on any of the vertical aerial photographs consulted. The only aerial photographs where the structures could be discerned were 1999-2000 oblique aerial photographs taken of the excavations and site. Due to the intertidal location of these features the aerial photographs did not provide sufficient control for NMP mapping. Therefore the mapping was located using survey plans (S19) from the excavation in 1999.

January 2010.
Preservation of the central stump has been completed and has been reunited with the remainder of the timbers, which have been on display at the King's Lynn Museum since April 2008.

July 2014.
Additional press attention followed a release of new information regarding the second timber circle (NHER 38044) at Holme.
The second timber circle was identified in 1999 and was closely monitored between 2001 and 2006. Dendrochronology suveys were carried out in 2011 and 2013, and the results were released to the press in 2014. See newspaper article (S62) for related discussion of this site. See NHER 38044 for details of the second timber circle.
