The old city of Damascus, enclosed by the city walls, lies on the south bank of the river Barada which is almost dry ( left). To the south-east, north and north-east it is surrounded by suburban areas whose history stretches back to the Middle Ages: Midan in the south-west, Sarouja and Imara in the north and north-west. These neighborhoods originally arose on roads leading out of the city, near the tombs of religious figures. In the 19th century outlying villages developed on the slopes of Jabal Qasioun, overlooking the city, already the site of the al-Salihiyah neighborhood centered on the important shrine of medieval Andalusian Sheikh and philosopher Ibn Arabi. These new neighborhoods were initially settled by Kurdish soldiery and Muslim refugees from the European regions of the Ottoman Empire which had fallen under Christian rule. Thus they were known as ''al-Akrad'' ''(the Kurds)'' and ''al-Muhajirin'' ''(the migrants)''. They lay  north of the old city.
