Alba Iulia Unification National Museum

The museum currently occupies two significant structures within the Alba Carolina Citadel. The primary exhibition space is the 'Babylon' building, constructed between 1851 and 1853 in the Romantic architectural style. Originally serving as a residence pavilion for Austro-Hungarian officers, it earned its name because officers from various ethnic backgrounds spoke 'all the languages of the world' there.

The building features thick walls over one meter high and contains more than 100 rooms. The second location is the 'Union Hall' (Sala Unirii), built between 1898 and 1900, which the museum received in 1958.

The museum's collection is chronologically organized from prehistoric times to the contemporary era, with particularly strong representations of the Dacian and Roman periods. A major focus is placed on the 1848 Revolution and the 1918 Union, housing documents, photographs, and memorial objects related to these events. Notable holdings include the credentials and telegrams of the Union, as well as artifacts from the Great Union celebrations. The collection has grown significantly through donations and archaeological excavations conducted by the museum's early directors.

The National Museum of the Union holds immense symbolic value as it is situated in the city where the Great Union of 1918 was proclaimed. The 'Union Hall' is the specific site where the historic unification of Transylvania with Romania took place. The institution is recognized for organizing approximately 50 temporary exhibitions annually, covering diverse themes beyond history, and for hosting major cultural events such as the 'Night of the Museums.' It stands as a vital repository for the bibliophilic assets and historical memory of the Romanian nation.
