El Raval is a compelling and interesting neighbourhood, with a long and chequered history. It's one of two districts bordering La Rambla, with the other being the established tourist area of Barri Gotic. Located near Barcelona's port, El Raval has always had an exciting, multicultural character, particularly popular with backpackers and revellers keen to check out the city's cutting-edge galleries and clubs. While having undergone a period of development, the area still remains slightly dangerous and tourists should be careful of pickpockets and avoid walking alone at night. El Raval is full of cool bars and funky cafes that beg to be explored, from Bar Marsella with its Art Nouveau interior, to London Bar, a run-down though stately place once frequented by artists like Hemingway, Picasso, and Mirò. Another great sight in El Raval is the Palau Guell, one of Gaudi's lesser-known masterpieces, featuring large parabolic gates decorated with beautiful ironwork.
