Gostiny Dvor
Subsequently, Quarenghi's structure went through many reconstructions. After the Revolution in 1923, the space was subdivided into offices altering the original design significantly. Recently a modern glass roof in 1995 was installed, when Gostiny Dvor was being converted into a fashionable exhibition ground. Nowadays, the edifice is used as the setting for fashion shows, business parties, and even Viennese balls. Montserrat Caballé and José Carreras were among those who performed at the New Year parties in Gostiny Dvor.
