Knights Templar secrets sought in Olympic dig

A massive archaeological dig has started today on the site of the 2012 Olympics.

And experts hope they may uncover two water mills believed to have been built on the site by the Knights Templar in the 12th century.

'This is an opportunity to chart and record the unique history of an area back to the first Londoners,' said David Higgins, the Chief Executive of the Olympic Delivery Authority.
