Built in 1898 to serve as a casino for the Austro-Hungarian army, the immense Unification Hall, whose vaults are supported by red marble pillars, is the location where the Unification Act proclaiming the unification of Transylvania with Romania was signed on the 1st of December, 1918. The Hall is part of the Unification Museum, opened in 1968 and sheltered by the former ôBabylonö edifice. The museum has several history sections, a library, and a permanent ethnographic exhibition focusing on the history of Transylvania.
