A kasbah was a place for the local leader to live and as a defense when the city was under attack. A kasbah has high walls which usually have no windows. Sometimes, they were built on the top of hills to make them easier to defend. Some of them were also placed near the entrance of harbors. Having a kasbah built was a sign of wealth of some families in the city. Almost all cities had their kasbah, this building being something necessary for the city to survive. Kasbah Ait Abu, Skoura, Morocco, 2010.
