With a total length of almost 13 kilometers, this used to be the largest souk in the world and had all of the shopping you could want to do from gold and silver, boxes, clothing, fabric and soap. Severely damaged during the civil war. A small part of the souk called al-Saqatiyah reopened in 2019. Bargaining is encouraged and if you know some Arabic it will get you a much better price.
