Developed as a "safe area" for a Lord or ruler to retreat to if needed - the Kasbah was a common sight in many Middle Eastern fortifications. Normally located in an area of a walled City, it likewise had high walls and no windows. Very simple and non elaborate entrances were incorporated into construction - all done on the "stealth" approach. A City with a Kasbah usually meant someone important lived nearby. These structures are probably the first example of "safe rooms" made. Some European Lords also incorporated them into their castle planning. They would be used for other purposes such as secondary armories etc.
