Damascus Univ. (1923), Damascus Oriental Institute of Music (1950), a technological institute (1963), an industrial school (1964), and the national museum (1919) are in Damascus. The old city lies south of the Barada, and the new town (greatly extended since 1926) lies north of the river. Points of interest include the Great Mosque (one of the largest and most famous mosques in the Muslim world), the quadrangular citadel (originally Roman; rebuilt 1219), a 16th-century Muslim monastery, and Azm palace (1749; now a museum and center for the study of Islamic art and architecture). The biblical "street which is called Straight" still runs in the old city from the east to the west gate, flanked by bazaars.
