CSO Ada, which takes its name from the abbreviation of the music ensemble known as the Presidential Symphony Orchestra, is the most modern stage in Ankara. CSO Ada, which hosts many important concerts, exhibitions and shows, is also located right next to the first CSO building built in 1947. The old stage, which stands out with its historical texture, is today called the "Historical Hall" and is still in use. CSO Ada with its modern look and the Historical Hall with its neoclassical design are both city elements worth visiting.
