THE haunt of witches for centuries, and a site shrouded in mystery, the Rollright Stones near Long Compton may have some secrets revealed this weekend and next weekend as part of National Archaeology Week.

Visitors on both weekends will enjoy free admission and guided tours by archaeologists including the chairman of the Rollright Trust, George Lambick, formerly director of the Council of British Archaeology, and Dr Gill Hey of Oxford Archaeology.

This weekend will also include a storyteller and next weekend a dowser will be giving lessons in the ancient art of water divining.

"This is an ideal opportunity to find out about the history and legends of one of Oxfordshire's oldest monuments," said trust spokesman Dohn Prout.

The stones, including a stone circle, a group of stones and a solitary rock, are said to date back to 3,800BC, making them older than Stonehenge.

Legend has it that a witch turned a king and his men into the stones and herself into a tree, and the site has been a meeting place for witches since the Tudor times.

Visitors will also be allowed to see the ghostly images on an inside wall of the site hut that left by a fire earlier this year.
