Britain has some of the best stone circles and Neolithic sites in the UK. They've inspired the imagination of historians, archaeologists and even poets. These prehistoric sites represent the very first civilisations in the UK and Europe and are still the subject of debate and mystery. Archaeologists tend to agree that they were used for religious rituals and even burials but ... they aren't certain that this was there main purpose. They've been linked to ancient druids, ghosts, crop circles and even alien visitations. Examples such as Stonehenge would have required the efforts of hundreds if not thousands of people so there is no doubt they were of extraordinary importance. This is our list of the top ten stone circles in the UK.
