Glasgow School of Art has revealed a full-scale prototype of a rebuilt Mackintosh library, three years after it was destroyed in a devastating fire.

The blaze tore through the west wing of the 108-year-old building, one of the best examples of Art Nouveau design in the world.

After six months of work, a prototype of one section of the rebuilt library has been unveiled, partly recreated using Charles Rennie Mackintosh's original designs.

Professor Tom Inns, director of Glasgow School of Art, said the event marked a "hugely significant step in the restoration of the Mackintosh Building".

He added: "From the outset we said that we would restore the building and restore it well."
