Pigalle is famous for being a tourist district, with many sex shops on Place Pigalle and the main boulevards. The neighborhood's raunchy reputation led to its World War II nickname of "Pig Alley" by Allied soldiers. The Divan du Monde and the Moulin Rouge, a world-famous cabaret, are both located in Pigalle.
The area to the south of Place Pigalle is devoted to the retail of musical instruments and equipment, especially for popular music. A section of the rue de Douai consists solely of stores selling guitars, drums, and musical accessories.
