The State Hall, the heart of the Austrian National Library, is one of the most beautiful library halls in the world. It is the biggest Baroque library in Europe.

The former Court Library was created in the first half of the 18th century as a private wing of the Hofburg imperial residence. Emperor Karl VI. ordered its construction. The library was built by Joseph Emanuel Fischer von Erlach according to plans of his father, Johann Bernhard Fischer von Erlach.

The impressive state hall of the library is almost 80 m long and 20 m high and is crowned by a dome that is magnificently decorated with frescoes by the court painter Daniel Gran. More than 200,000 volumes are exhibited here, among them the comprehensive library of Prince Eugene of Savoy as well as one of the largest collections of Martin Luther’s writings from the Reformation Era.
