‘It’s magical’: prehistoric mines in Norfolk to reopen to visitors

English Heritage hopes new entrance at Grime’s Graves will mean more people can explore neolithic site

“I’ve spent a lot of time crawling around [down here], and you can go into certain spaces where you see someone’s tool and think: someone just put that down 4,500 years ago, and it’s still here,” she says.
