One of the greatest Neolithic monuments is located in Thornborough near Ripon. There is not much to see at ground level but seen from above you can see the vast banks and 3 large circles which have been built there as part of a massive earthworks. These are dated from 3500BC which is over a thousand years earlier than the pyramids (Yorkshire folk not to be outdone). This area is sometimes called the Stonehenge of the North, however visitors should be aware there are no giant stones on this site. Each circle measures 240 meters across with earth banks which stood at least 1.5meters high at their completion. The banks were also covered in Gypsum crystals which would have glistened and made the rings stand out as huge white rings in the landscape.
What was its purpose? frankly we don't know, there were no written records at the time so it is very much open to speculation.
