Forgotten ‘Stonehenge of the north’ given to nation by construction firm

Two sections of the Thornborough Henges come off Historic England's at-risk register after donation

Two enormous and thrillingly mysterious ancient monuments, part of a complex regarded as the Stonehenge of the north, have been given to the nation and will come off England's heritage at-risk register.

The Thornborough Henges, near Ripon, in North Yorkshire, are three huge, human-made, enclosed earth circles. Each is more than 200 metres in diameter and they date from 3500BC to 2500BC, making them late neolithic/early bronze age monuments.
