Cut off from the landscape and enclosed in this huge human-made arena, our ancient ancestors would have felt "centred within nature" and could even have had a "cosmic experience", they say.
According to Dr Jennifer Wexler, this once "historically ignored" site unlocks the mystery of the Neolithic people who built them, but who left behind no written record of their existence.
Dr Wexler, senior properties historian for English Heritage, said the earthworks contained "layers of history" which spanned thousands of years.
Mr Savage said: "The trees on the northern henge were a later addition and not part of the original concept, but they have preserved the banks and protected them from erosion."

Dr Wexler added that everyone involved was "so excited" to have the Thornborough Henges reunited and ready for people to retrace ancient footsteps.
