The Great Exhibition of 1851 was something to behold for the 6 million Victorian patrons who travelled to London's Hyde Park to see it. It was a triumphant showcase of the most extraordinary achievements of the Victorian age from industry, culture and engineering - gathered from all four corners of the globe. As visitors walked the 8 miles of exhibitions, they would have seen everything from the sublime to the absurd: the world’s largest diamond, a contraption to predict the weather using leeches, the world's first public flushing toilets and a two-person piano.

The enormous glass and iron building that housed the exhibition was big enough to house four St Pauls Cathedrals and its construction involved some of the most famous engineers of the Victorian age - Brunel, Faraday, Stephenson and Paxton.

To tell Dan the story of the Crystal Palace is historian and conservationist Steven Brindle.

Produced by Mariana Des Forges and edited by Tim Arstall.
