Fresh calls to improve fencing around Silbury Hill are being made as dozens of walkers have been seen hiking to the top of the ancient mound near Avebury.

Marlborough police say: "We have received a number of calls from members of the public today regarding groups climbing Silbury Hill.

"We would like to remind everyone that this historic monument is not accessible by the public. Please respect the preservation of this artifact."

"I drive past here more than 2-4 times a day quite often," posted Sam Dodd.

"Always see groups walking up the hill. Needs better fencing around the base."

Visit Wiltshire states: "There is no public access to the hill, in order to protect this important archaeological site. However, you can walk around the base of the mound and admire the view of this mysterious monument standing tall above the pretty Wiltshire countryside.

Silbury Hill can be seen for miles around and incorporated into some lovely walks in the surrounding area. You can take half an hour to follow a short loop all the way around the base of the hill. Or if you fancy something longer you can walk between a number of the local World Heritage Neolithic sites including the Avebury Stone Circle and West Kennett Long Barrow."
