Kasbah

A kasbah, also spelled qasbah, qasba, qasaba, or casbah, is a fortress, most commonly a North African citadel or fortified quarter of a city. Spanish has the equivalent term alcazaba, derived from the same Arabic word. By extension, the term can also refer to a medina quarter, particularly in Algeria. In various languages, the Arabic word, or local words borrowed from the Arabic word, can also refer to a settlement, a fort, a watchtower, or a blockhouse.
