What it is

The souq or bazaar is the linear, often roofed network of trading lanes at the commercial heart of the Islamic city, with shops grouped by trade along covered streets radiating from the congregational mosque. At its core stood the qaysariyya, a secure, gated and lockable hall for valuable goods such as textiles, jewellery and books, often held as waqf to fund nearby pious institutions. Crafts were arranged hierarchically, with clean trades like booksellers and perfumers near the mosque and noxious ones such as tanners pushed to the edge. Vaulted or wooden roofing shaded the lanes and let trade continue through heat and rain.

Why it matters

The covered bazaar gave the Islamic city its characteristic dense, introverted commercial core, organising trade, finance and endowment income into a single roofed armature. As a durable urban form it survives intact in cities from Aleppo and Isfahan to Istanbul and Marrakesh.
