Dorset mega henge may be ‘last hurrah’ of stone-age builders

Study of Mount Pleasant site suggests it was constructed over decades, not centuries

An intense burst of building work took place in Britain at the end of the neolithic period, possibly as a final hurrah" by stone-age man and woman as they sensed the approach of fundamental change, research on a prehistoric monument in Dorset has suggested.

A study of the Mount Pleasant mega henge", a sprawling site near Dorchester, has found it was not constructed over centuries as had previously been thought but in as little as 35 years.
