On Monday, June 16, a full-day police closure was imposed on Heldenplatz and Herrengasse. The reading rooms at Heldenplatz, in the Picture Archive and Graphics Collection and in the Music and Esperanto Collection as well as the House of Austrian History will therefore remain closed all day.
On June 21, 2025 the State Haal will only be open starting 1 p.m.
The reading rooms on Heldenplatz and the reading rooms of the collections are closed on public holidays. This also applies to Thursday, June 19 (Corpus Christi).
Regular opening hours apply in the museums; in addition, all museums are open on Whit Monday.
In November 2018, the House of Austrian History opened in the rooms of the Neue Burg to mark the 100th anniversary of the Republic of Austria. A new museum was thus added to the Austrian National Library. It is concerned with the mediation of and lively dialogue on Austrian contemporary history.
