There are mosques all over the medina; interiors are off-limits to non-Muslims. The finest include Mosque of Youssef Dey, Tunis' first Ottoman-style mosque (1616), designed by Andalusian architect Ibn Ghalib in a colourful mishmash of styles. It was surrounded by Turkish souqs - El-Trouk (tailors), El-Berka (slaves) and El-Bechamkia (slippers) and catered to the Turkish traders.
Look out for the minaret crowned with a miniature green-tiled pyramid - this was the first, much-copied octagonal minaret in Tunis, serving as propaganda for the new masters. The mosque contains the tombs of Youssef Dey and his family - another innovative Ottoman custom.
