Once a year, the city of Salé celebrates the birth of Muhammed (the prophet of Islam) with a Candles Convoy, also known as the Festival of Cierges. Accompanied by musicians and flag bearers, a long parade of men in colourful attire and carrying huge wax lamps comprised of thousands of sculpted and dyed pieces moves through the city's main streets to arrive at the Mausoleum of Sidi Abdallah Ben Hassoune, the city's saint.
