The medina markets (souqs) were organised into different commercial areas. Refined trades surrounded the Zaytouna Mosque, while dirtier businesses such as tanners or blacksmiths stayed on the outskirts. The markets are either named after their traditional trade or their founding community, such as Souq el-Grana - the Livornese Jews' Souq. The main markets include the Souq el-Attarine - the Perfume Makers' Souq, dating from the 13th century, near the Zaytouna Mosque.
Today it's largely souvenirs, but there are plenty of essential oils too. The quilted satin baskets on sale are for wedding gifts.
