Norfolk's most ancient attraction has scooped national attention after being named among England's best historical sites.

Grime's Graves near Thetford features a complex of prehistoric flint mines dug 4,500 years ago and is the country's oldest human-made underground area.

The site is nationally acclaimed and experts describe the graves as an ancient industrial hub, the Neolithic equivalent of Yorkshire’s cotton mills or South Wales’ steelworks.

The Telegraph also suggests a stay at the nearby Elveden Inn with its "contemporary rooms" and "no-nonsense" pub food.

Jennifer Wexler, a historian from English Heritage, said: “What makes Grime’s Graves such a special place is that there are still so many secrets to be unlocked.

"To this day, most of the over 400 pits remain untouched and geophysical surveys suggest that the mines covered a much greater area."
