The UK's world-famous Stonehenge has been attracting tourists for thousands of years.
Not only is it protected as a UNESCO World Heritage site — for its status as the most architecturally sophisticated prehistoric stone circle in the world — it has also mystified people for centuries.
Archaeologists believe the megalith was constructed from 3000-2000BC, but the pattern in which the stones are arranged is still being explored today. Theories about its origin range from the academic worlds of archaeology to explanations from mythology and the paranormal.
According to Professor Michael Parker Pearson of University College London, who has studied the sacred site over the last 10 years, Stonehenge was the land of the dead. In an interview with the New York Times, Dr Parker Pearson said early Britons gathered at Durrington Walls — another stone monument in the Stonehenge World Heritage Site, about 3km north of Stonehenge — to feast before proceeding to Stonehenge to honour their ancestors.
