A monumental mall, Arenas de Barcelona opened in 2011 in a re-purposed bullring with over 100,000 square meters (1000 sq. ft.) of shops, eateries, movies, a jogging track, 360-degree roof terrace and culture - including the Museum of Rock. Built in the late 19th century, the Plaça de Toros de les Arenes had been unused for decades when Richard Rogers, architect of the Pompidou Center in Paris, was hired to convert it while maintaining the red-brick exterior. Bullfighting, BTW, is now outlawed in Barcelona.
