The Military Casino (Romanian: Cazinoul Militar), one of the oldest buildings of Timișoara, is situated on the west side of the city's Liberty Square.

[2] The Military Casino is actually the pavilion A of the building complex formally known as Casern 901 (Romanian: Cazarma 901).

[6] The large ballroom upstairs played an important role in the social life of the young people, as the famous officers' balls were held here.

[8] Otto Roth proclaimed the Banat Republic in this building on 31 October 1918, but Aurel Cosma requested the Romanian officers to leave the casino.

They went to the Kronprinz Hotel (in the current building of the Opera House)[9] where they established the National Romanian Military Council.

[8] In 2002 two 75 mm Reșița Model 1943 anti-tank cannons were placed in front of the terrace,[6] but they were removed after the square was redesigned in 2015.
