The Kasbah of Algiers is at the heart of the city of Algiers, Algeria, located on a huge crescent bay hemmed in by steep hills and facing north over the Mediterranean. The Kasbah spreads up a hillside above the port to a hill-top citadel, a warren of narrow winding alleys and densely packed white-washed houses.
It was mostly built between the 16th and 18th centuries during a period of allegiance to the #Ottoman sultan. The city’s wealth was derived from piracy and from its position at the trailhead of the trans-Saharan caravans. By the end of the 18th century it had grown into a flourishing, well-fortified city of some 100,000 people. Many of the prominent buildings – mosques and grand mansions of the wealthy classes from the Ottoman period - have survived, and are undergoing restoration.
