Type of fortress in Arab or Islamic regions

A kasbah ('/k//æ//z//b//ɑː/, also /US/'/k//ɑː//z// /; قَـصَـبَـة, , Maghrebi Arabic: ), also spelled qasba, qasaba, or casbah, is a fortress, most commonly the citadel or fortified quarter of a city. It is also equivalent to the term alcazaba in Spanish (alkaˈθaβa), which is 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.

The term qasaba was historically flexible but it essentially denotes a fortress, commonly a citadel that protects a city or settlement area, or that serves as the administrative center. According to architect and restorer Leopoldo Torres Balbás, the Alcazaba of Málaga is the prototype of military architecture in the Taifa period in Al Andalus, with its double wall and many fortifications. Its only parallel is the castle of Krak des Chevaliers in Syria. Examples of other alcazabas in Spain include the Alcazaba of Almería, the Alcazaba of Antequera, the Alcazaba of Badajoz, the Alcazaba of Guadix, the Alcazaba of Mérida, the Castle of Molina de Aragón, the Alcazaba of Alcalá la Real and in the Alcazaba of the Alhambra in Granada. In Morocco, the term "kasbah" is also used in predominantly Amazigh regions to denote a fortified residence (tighremt in Amazigh languages), often built of mudbrick, such as the Kasbah of Telouet or the Kasbah Amridil. In southern Tunisia, the term is sometimes applied to some fortified granaries (also known as ksour).

The word kasbah may also be used to describe the old part of a city, in which case it has the same meaning as a medina quarter. In Algiers, the name qasaba originally referred to the upper part of the city which contained the citadel and residence of the rulers. Following the French conquest of the country in 1830, most of the historic lower town of Algiers was demolished and remodeled along European lines. The only part of the old city that remained relatively untouched was the upper town, thus known as the "Casbah" of Algiers. Another book describes these towers as follows: "Apparently unique to Asir architecture are the qasaba towers. Controversy surrounds their function – some argue that they were built as lookouts, and others that they were keeps, or even granaries. Perhaps it is a combination, although the right position of a watchtower, on a hill top, is the wrong place for a keep or granary." Archaeologists have found images of similar towers in the ruins of Qaryat al Fāw, in the Rub' al Khali of Saudi Arabia, that date from between the 3rd century BCE to the 4th century CE. "Homes rose two stories, supported by stone walls nearly two meters (6') thick and boasting such amenities as water supply systems and second floor latrines. One eye catching mural faintly depicts a multi story tower house with figures in the windows: Its design resembles similar dwellings today in Yemen and southern Saudi Arabia." "Most of the qasabas have a circular plan, although some are square. Sometimes they have a band of quartz stones just below the windows or framing the windows – one well preserved example is at the top of Wadi Ain. The remains of a martello tower like stone structure are just off the dirt track north of Al Masnah. It appears to be an interesting antecedent of the Asir farmhouse and perhaps closely related to the qasaba. It is in ruins now, but was once a dwelling and is strongly defensive."
