While in Wiltshire earlier this month, I stayed in the village of Avebury, which lies within the world’s largest megalithic stone circle, and is about a mile north of Silbury Hill (see previous post at Exploring-the-barrow-downs-of-wessex
Constructed over several hundred years during the Neolithic period from around 3,000 BC to 2,600 BC, a large henge (a bank and a ditch) with a large outer stone circle encircles part of Avebury village. Two separate smaller stone circles are located closer to the centre of the henge.
The outer stone circle is 332 metres in diameter with a circumference just over 1,000 metres and encloses two smaller stone circles near its centre. The available evidence suggests that in the early Neolithic, Avebury and the surrounding hills were covered in dense oak woodland, and as the Neolithic progressed, the woodland around Avebury and the nearby monuments receded and was replaced by grassland.
