Norfolk was a centre of metalworking and by the Late Bronze Age northern Norfolk had developed into a major area of production. There were also throwbacks to the earlier ages and one such type were the monuments. A significant find was discovered in 1998 between the high and low tidal limits off the north west coast of Norfolk at Holme-next-the-Sea. A ring of timbers was found and within it an upturned tree stump with its roots above the sand. The remains were excavated in 1999 and the samples taken dated it to 2049 BCE.
