Crop circle enthusiasts from all over the world will converge on Marlborough this weekend for the 14th Circles of Knowledge conference.

The conference is organised by the Wiltshire Crop Circle Study Group and will take place in the Memorial Hall at Marlborough College this Saturday and Sunday.

It will include lectures and films focusing on crop circles and subjects associated with them. Speakers include Francine Blake, Bert Janssen and Jay Gouldner who will speak on the crop circles themselves while Glenn Broughton, Peter Knight, Maria Wheatley and Lucy Wyatt will discuss sacred sites and landscapes.

Clare Oatley, a member of the conference team, said: “The weekend event attracts people from all over the world, who travel to Wiltshire to visit the crop circles.

“This year over 50 crop formations have appeared in the fields of Wiltshire, Hampshire, Dorset, Somerset, Gloucestershire and beyond. Early designs can be found in oilseed rape from May onwards, continuing into barley and wheat as the summer goes on.

“Formations in previous years have also been found pressed into maize into the autumn.”

Tickets are available for either Saturday, Sunday or the whole weekend and activities include guided visits to Avebury and West Kennett Long Barrow. For more information go to
