 Galicia was subject to the Austrian part of the Dual Monarchy, but the Galician Sejm and provincial administration, both established in Lviv, had extensive privileges and prerogatives, especially in education, culture, and local affairs.The city grew rapidly, becoming the 4th largest in Austria-Hungary, according to the census of 1910.Many "Belle Époque" public edifices and tenement houses were erected, and buildings from the Austrian period, such as the opera theater built in the Viennese neo-Renaissance style, still dominate and characterize much of the centre of the city.
