THE origins and purpose of Stonehenge have always been shrouded in mystery and now the ancient monument has made it on to a list of things Britons find most confusing.

‘Why and how Stonehenge was built’ came 28th in a survey of what people think are the most confusing things – and it wasn’t the only one on the list for Wiltshire, with crop circles coming in at 35th and Swindon’s Magic Roundabout at number 48.

The survey, which polled 4,979 people between the ages of 16 and 65, placed foreign call centres, algebra, what women see in Russell Brand and why Cheryl Cole is still with her husband were named as the top four biggest confusions in Britain.

Birmingham’s Spaghetti Junction ended up 37th in the survey survey, conducted by Confused.com.
