Seahenge (Holme I) was a Bronze Age timber circle discovered in 1998 on Holme Beach in Norfolk, England, after coastal erosion exposed it. Built in 2049 BC, the monument consisted of 55 oak posts forming a circle 6.6 metres in diameter around an inverted oak tree stump with roots uppermost. Researchers believe it may have served as an excarnation site where bodies were placed atop the upturned roots for sky burial. Its excavation in 1999 by the Norfolk Archaeological Unit proved controversial, with local opposition from residents and druids. The timbers are now preserved at Lynn Museum in King's Lynn.
