Marden Henge

Marden Henge is the largest stone age henge enclosure in the United Kingdom, located in the village of Marden, Wiltshire, situated within the Vale of Pewsey between the World Heritage sites of Avebury and Stonehenge.
Encompassing an area of 15 hectares (37 acres) and under the care of English Heritage, antiquarian accounts of the site describe a huge mound within the enclosure called Hatfield Barrow, which collapsed after excavation by William Cunnington in the early 19th century. Today, Marden Henge has been damaged by ploughing, and no longer has any standing stones.
The site was excavated by Geoff Wainwight in 1969. He excavated the North entrance, and found a timber circle, and Grooved Ware pottery, similar to Durrington Walls. The finds are at Wiltshire Heritage Museum in Devizes, where there is also a small display.
In 2010, the henge and surrounding area were investigated through aerial, geophysical, and field survey. During the dig, a Neolithic building was discovered, described as the best preseved Neolithic building in England.
