Paris has the Eiffel Tower, London has Big Ben – and Marrakech has the Koutoubia Mosque. Towering over the square (and over the whole of the Medina), it’s the highest point in the city by a long way and the landmark with which visitors become most acquainted. ‘Koutoubia’ means ‘of the booksellers’: the mosque acquired its name because of the profusion of book-traders that used to gather around it. The main structure was built in 1158, with the minaret added later by Yacoub El Mansour. Unfortunately it’s only the outside you’ll be seeing unless you’re a Muslim, and that from a slight distance, since non-Muslims are barred from the interior and most of the surrounding area.
