A kasbah (/, - , -/; Arabic: قصبة qaṣbah), also known as qasaba, gasaba, and quasabeh, or in older English casbah, or qasbah and qassabah in India, is a type of medina, or fortress (citadel). The word kasbah comes from the Arabic القصبة, meaning "central part of a town or citadel".
In Morocco and in Iberia, the Arabic word form of kasbah frequently refers to multiple buildings in a keep, a citadel, or several structures behind a defensive wall. The Spanish word alcazaba is a cognate naming the equivalent building in Andalusia or Moorish Spain. In Portuguese, it evolved into the word alcáçova. In Catalan, the evolution resulted in "alcassaba". A kasbah was a place for the local leader to live and a defense when a city was under attack. A kasbah has high walls, usually without windows. Sometimes, they were built on hilltops so that they could be more easily defended. Some were placed near the entrance to harbors. Having a kasbah built was a sign of wealth of some families in the city. When colonization started in 1830, in northern Algeria, there were a great number of kasbahs that lasted for more than 100 years.
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. Some of the prominent examples of kasbah as an old city is the Casbah of Algiers and the Casbah of Dellys. In Turkish and Urdu the word kasaba refers to a settlement larger than a village but smaller than a city; in short, a town. In Serbo-Croatian, kasaba (Cyrillic: касаба) means an undeveloped, provincial small town. In India, a qasbah is a small town distinguished by the presence of Muslim families of rank.
In the al-Baha and Asir provinces of Saudi Arabia and in Yemen, the word "qasaba" usually refers to a single stone or rock tower, either as part of a tower house or a tower isolated on a hilltop or commanding a field. The Encyclopædia Britannica defines it as: "Ancient qasaba (“towers”) found in the province were used as lookouts or granaries." 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." Archeologists have found images of similar towers in the ruins of Qaryat al-Fāw, in the Rub' al-Khali or the Empty Quarter of Saudi Arabia, that date from between the third century BCE to the 4th century or our era. "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 examples 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." One account says about a traditional village in Al-Baha, Saudi Arabia: "Even the road that leads to the village is impressive, and several historical stone and slate towers dot the way. Al-Bahah Province is known as the region of 1001 towers, once built to protect villages, roads and plantations from rivalling tribes. Today, these towers are abandoned, and many of them are partially or completely in ruins."
