Salzburg's "Old Town" (Altstadt) has internationally renowned baroque architecture and one of the best-preserved city centres north of the Alps. It was listed as a UNESCO World Heritage Site in 1997. Host to three universities and a large population of students, Salzburg is noted for its attractive setting and scenic Alpine backdrop.
Salzburg was the birthplace of 18th-century composer Wolfgang Amadeus Mozart. In the mid‑20th century, the city was the setting for parts of the musical play and film "The Sound of Music".
