The Castilian word alcaiceria takes its root from the Arab word al-qaysariyya based on the Latin Caesar, which itself comes from the Greek term for Imperial or Caesar’s market. This term alludes to the emperor Justinian, who granted the Arab people the right to trade in silk. In the Orient, the term used for this type of construction is the Persian word khan or caravanserai. The word alcaiceria is used to describe a group of shops belonging to the royal patrimony and used to sell silk and other precious materials imported from the Orient. Among the cities, which boast an alcaiceria, we find Granada, Cordoba, Seville and Toledo and their silk bazaars have been compared in size to the one found in Fez, even though the Moroccan city is much larger.
