The memorial museum dedicated to the great Romanian politician Aurel Lazar was inaugurated on December 1, 2008 in the house at no. 13 of the street that bears his name. The house, which belonged to the family of the lawyer Dr. Aurel Lazăr, is a true monument of Romanian history in that, on October 12, 1918, the text of the Declaration of National Independence of the Romanians from Transylvania, Banat, Crişana and Maramureş was drawn up here , a document of particular importance, which became, since its launch, the manifesto-programme of the political movement for the national liberation of the Romanians from Transylvania, a movement that culminated in their acquisition, on Dec...ember 1, 1918, of full independence. The basic exhibition reconstructs the environment in which Aurel Lazar's family lived in the first half of the 20th century. The largest part of the collection was donated to the museum by Valentina Lazăr, Aurel Lazăr's daughter-in-law, the most representative pieces being: an eclectic-style living room composed of a table with carved oak legs, a sofa, two chairs with upholstered arms, two smaller chairs. An important piece of the collection is a black armchair, which, according to Mrs. Valentina Lazăr, belonged to the desk on which the Oradea Declaration of Independence was drawn up on October 12, 1918. The main theme of the exhibition is the participation of the Bihoreans in the Great Union at Alba Iulia on December 1, 1918, but also the events preceding and following this memorable date in Romanian history. Visitors are greeted by a "time tunnel" in which personalities and events related to the Bihor lands are presented, which speak about the Romanian nation and the idea of national unity. Interactive maps, the credentials of those present at Alba Iulia, as well as original documents and objects from that period (military uniforms, flags and objects that belonged to Romanian soldiers) can be consulted within the exhibition.
