RabaḠ() refers to the suburbs of seventh- to eighth-century cities in Central Asia, including what is now the Turkistan Region in southern Kazakhstan, Iran, and Afghanistan.
This term, in the Andalusë Arabic form of ar-rabÃÂá¸Â, was borrowed into Spanish as ' and into Portuguese as '.
A typical qalÿat ("fortress") in Central Asia was based on a tripartite city model: citadel, shahristan (residential area inside the walls), and rabaḠ(suburb). This city model is valid not only for Central Asian city typology, but is also used to describe similar city types elsewhere in the Muslim world.
