Knight Frank is selling a 4,500-year-old Neolithic monument known by historians as the Stonehenge of the North.
The most northerly of the three Thornborough Henge earthworks, near Richmond in North Yorkshire, is being sold on behalf of local landowner Richard Bourne-Arton, after negotiations with English Heritage collapsed over the price.
The price tag is £200,000, and it comes with 7.26 acres of adjoining woodland, but there is little that a prospective buyer could actually do with the site.
“It’s the same thing as… a Ferrari 250 GTO or a piece of art… you buy it because no one else can,” said Claire Whitfield, rural consultancy partner at Knight Frank.
The henges include giant circular structures more than 200m in diameter and which date from between 3,500 and 2,500BC.
The other two henges are not available, having been given to the nation at the start of the year by Tarmac, the construction company, which owned the land they sat on. These two sites, operated by English Heritage, opened to the public free of charge in February.
