Woodhenge

Neolithic (New Stone Age) monument 4 km/2.5 mi northeast of Stonehenge, Wiltshire, England. The structure is composed of six concentric circles of wooden posts, the outermost being 40 m/130 ft in diameter. The posts are laid out very precisely, suggesting the possible use of a standard measurement with significance in ritual practice.

Woodhenge, which possibly predates Stonehenge, may form a peripheral part of a greater complex centred on the nearby henge monument of Durrington Walls. This large circular earthwork, with a bank and ditch about 450 m/1,500 ft in diameter, probably contained several structures similar to Woodhenge.

The site of Woodhenge was one of the first to be discovered by aerial photography in 1925.
