In the early 1970's Crop circles used to be unexplained patterns that were generally found in corn fields - Hence the terminology 'corn circles'. However, in more recent years teams of 'circle-makers' within the South of England have openly admitted to creating some of these fantastic formations, and have constructed them in crops as diverse as Linseed and Rapeseed.
Most frequently these art forms have appeared near ancient monuments that are themselves considered to be built on sites of powerful natural energies. Many people believe that its of no coincidence that the phenomenon appears close to these ancient sites, and some have even reported crop circles forming in under 20 seconds under incandescent or brightly coloured balls of light.
Whatever you chose to believe about the crop circle phenomenon, there is no doubt that the circles are responsible for attracting huge amounts of media attention, which consequently results in thousands of visitors coming to the UK every year in the hope that they will witness these strange sensations.
