Security establishments in Andalusia distinguished themselves with distinctive architectural designs that reflect their functional nature. These facilities encompassed various roles, including judiciary and police functions, each characterized by specific architectural features. In this research, we aim to explore the urban aspect of these significant structures, whether related to the judiciary or police roles, including considerations such as courthouses, prisons, and the like. Our investigation is based on the texts found in Al-Mu'jam Al-Mu'arab by Al-Wansharisi.
