Montmartre is known for the white-domed Basilica of the Sacré Cœur, located at the summit of the butte Montmartre, the highest point in Paris. Many artists had studios or worked around the community of Montmartre such as Salvador Dalí, Modigliani, Claude Monet, Pablo Picasso and Vincent van Gogh… Downhill to the southwest is the red-light district of Pigalle. That area is, today, largely known for a wide variety of sex shops and prostitutes. It also contains a great number of stores specializing in instruments for rock music. There are also several concert halls, also used for rock music.
