Jemaa el Fna Square, in the heart of the medina, waits for the sun to go down before offering up its street shows, multiple stalls, crowds, noises and cries, music and improvised greasy spoons. The highlight of the evening is the street art of "halka" in which words are interpreted in a special way, and tales, stories and songs are reinvented for curious onlookers and performance fans who always ask for more. Jemaa el Fna Square has been designated a "masterpiece of oral and intangible heritage of humanity" by UNESCO.
