On the radio news, this morning:
WORK to conserve and stabilise the 4,400 year old Silbury Hill in Wiltshire began today.
English Heritage, working with specialist engineers Skanska, has exposed the door in the side of the Hill leading to the tunnel excavated by Professor Atkinson in 1968.
Engineers are to reopen a tunnel that goes deep inside the ancient monument of Silbury Hill in Wiltshire.
The tunnel, dug in 1968, was the last made over many centuries by archaeologists exploring the site.
Engineers are planning to stabilise the 5,000-year-old structure, which is believed to be the world’s largest man-made prehistoric mound.
