The Cotswolds and the Berkshire Downs were dense with ritual activity in the 4th and 3rd millennia BCE — long before Stonehenge was completed. Several sites survive within an easy day's drive of Oxford, ranging from a chambered tomb older than the Pyramids to one of England's largest surviving stone circles.
Below are the Neolithic-era sites currently covered on OxfordLocal. The tag also picks up later Bronze Age monuments built on the same sacred ground; for those, see also prehistoric and ancient.
A 4,500-year-old stone circle on the Oxfordshire–Warwickshire border, with an older Neolithic burial dolmen and a probable Bronze Age standing stone — the most accessible major prehistoric site within reach of Oxford.
A Late Neolithic henge and stone circle at Stanton Harcourt, levelled by a wartime airfield, then chewed by gravel quarrying, then reconstructed almost from scratch between 2002 and 2008.
An Early Neolithic chambered long barrow on the Ridgeway, completed around 3430 BCE — among Britain's best-preserved Severn-Cotswold tombs and a long day's walk from the Uffington White Horse.
