Seahenge

Seahenge is a Bronze Age timber circle and central tree trunk feature first exposed by coastal erosion on the Norfolk coast of England in 1998. It is an archaeological site notable for its timber construction and its preservation in a coastal, intertidal environment.

The feature consisted of a ring of upright wooden posts with a central stump and was interpreted as a ceremonial or ritual monument from the early Bronze Age. Its discovery attracted archaeological excavation and subsequent conservation work.

Archaeologists excavated and removed the timber elements after discovery to conserve them and to study construction and dating; research placed the structure in the early Bronze Age. The site and finds prompted public debate about conservation and in situ preservation versus removal.

Seahenge lies on the intertidal beach near Holme-next-the-Sea on Norfolk’s north Norfolk coast, exposed by tidal action and coastal erosion on the North Sea shoreline.

• Discovery: Discovered and excavated after exposure by coastal erosion in 1998, the timber circle dates to the Bronze Age and was removed for conservation.
• Tidal exposure: The site is intertidal and its remains are subject to tidal exposure and coastal change, so visible features depend on tide and erosion.
