Djemaa El-Fna is a square and market place in Marrakesh's medina quarter (old city). The origin of its name is unclear: Jemaa means "congregational mosque" in Arabic, probably referring to a destroyed Almoravid mosque. "Fanâʼ" or "finâ'" can mean "death" or "a courtyard, space in front of a building." Thus one meaning could be "the mosque or assembly of death," or "The Mosque at the End of the World". A more likely explanation is that it refers to a mosque with a distinctive courtyard or square in front of it. The place remains the main square of Marrakesh, used equally by locals and tourists. During the day it is predominantly occupied by orange juice stalls, youths with chained Barbary apes, water sellers in colourful costumes with traditional leather water-bags and brass cups, and snake charmers who will pose for photographs for tourists. As the day progresses the entertainments on offer change: the snake charmers depart, and in the afternoon and evening the square becomes more crowded, with Chleuh dancing-boys (it would be against custom for girls to provide such an entertainment), story-tellers (telling their tales in Berber or Arabic, to an audience of appreciative locals), magicians, and peddlers of traditional medicines. As dark descends the square fills with dozens of food-stalls, and the crowds are at their height.
