It was one of the finest examples of Art Nouveau architecture in the world, but in May 2014 fire ripped through the Glasgow School of Art.

Forensic archaeologists have begun sifting through the rubble to see what can be saved from Charles Rennie Mackintosh's architectural masterpiece.

They hope to find items that could be restored or provide information for the building's restoration.

I took a look around the wreckage.
