The Austrian National Library (Österreichische Nationalbibliothek) is the largest library in Austria and one of the most important cultural and historical institutions in the country. Located in Vienna, the capital city of Austria, the Austrian National Library is housed in the magnificent Hofburg Palace complex, which also includes the Austrian State Archives and the Austrian Museum of Ethnology.

Founded in 1368 by Duke Rudolf IV, the Austrian National Library has a rich and storied history that spans over six centuries, making it one of the oldest and most prestigious libraries in Europe. The library's extensive collections encompass a wide range of materials, including manuscripts, rare books, maps, globes, prints, photographs, and audiovisual materials, as well as a comprehensive collection of Austrian and international publications that document the cultural, intellectual, and scientific heritage of Austria and the world.

One of the highlights of the Austrian National Library is its stunning State Hall (Prunksaal), a magnificent Baroque hall that was built between 1723 and 1730 by the renowned architect Johann Bernhard Fischer von Erlach. The State Hall features a breathtakingly beautiful and ornate interior adorned with elaborate stucco decorations, frescoes, and gilded sculptures, as well as a magnificent dome ceiling with a stunning allegorical depiction of the Habsburg Empire's virtues and achievements.

The State Hall is home to the library's impressive collection of over 200,000 volumes of books and manuscripts, including rare and valuable works from the Middle Ages to the present day. Some of the most notable treasures housed in the State Hall include the 15th-century Gutenberg Bible, one of the first books printed using movable type, and the Codex Vindobonensis, a 6th-century illuminated manuscript of the Greek epic poem "Iliad" by Homer.
