Tourism brings revenue to Florence, but also creates certain problems. The Ponte Vecchio, The San Lorenzo Market and Santa Maria Novella are plagued by pickpockets. The province of Florence receives roughly 13 million visitors per year and in peak seasons, popular locations may become overcrowded as a result. In 2015, Mayor Dario Nardella expressed concern over visitors who arrive on buses, stay only a few hours, spend little money but contribute significantly to overcrowding. "No museum visit, just a photo from the square, the bus back and then on to Venice... We don’t want tourists like that," he said.
