The images of the Glasgow School of Art going up in flames again were like a bad dream. The glowing orange inferno, caught on mobile phones, brought back memories of the fire four years ago which destroyed the most beautiful space in the building, the library, surely one of the most remarkable rooms in the history of architecture. But this time the damage has been more far reaching. It looks as if the entire interior has been gutted. The building was being restored but now seems to have been utterly destroyed. All that remains is the masonry shell which will have been dangerously damaged by the very high temperatures.
