For me it began with a disquieting tweet from a Glasgow contact, around lunchtime on Friday, May 23. “Is the Art School on fire?” she asked. Yes, she confirmed when I urgently asked for information, it seemed to be gushing smoke. Then the photos and newsreel footage started to appear. It was looking worse and worse, especially when flames burst out of the top floor of the building. The horror from the world’s architecture community was real and immediate. Many, including me, were in tears. There is only one Art School in Glasgow: the one that is celebrated worldwide as Charles Rennie Mackintosh’s masterpiece. An extraordinary synthesis of Scottish Baronial, Arts and Crafts, Art Nouveau, and Japanese styles with industrial-modern construction methods, built in two phases from 1897 and 1909. Its interiors, especially its extraordinarily rich, timber-lined library with its purpose-designed furniture and fittings, also show the guiding hand of Mackintosh’s artist-designer wife Margaret MacDonald. This much-loved building was still in use exactly as designed.
