Opposite the Salzburg Residenz is the New Building (Neugebäude), erected in 1602 as the Archbishop's guesthouse and enlarged in 1670. 

Now home to provincial government offices and the Salzburg Museum, the building is famous for its carillon (Glockenspiel). Built in 1702, it contains 35 bells that play tunes from Mozart's vast repertoire three times per day (7am, 11am, and 6pm, guided tours available).

 A highlight of the experience is hearing the famous Salzburg Bull, the organ in neighboring Hohensalzburg palace, respond to the carillon with a chorale.
