There are places people leave and places people go. Naples might be Italy's third-biggest city, but it is losing those some of those people all the time. The city was once one of the industrial engines of Italy -- a history still evident from the husks and dirt of factories in parts of its centre -- and its promenades still hold some of the splendid grandeur of a city known for its contribution to the arts, travel, literature, food, football and crime. But in recent years, like many cities built on industry and manufacturing, some of that glory has faded away. And its young people have left, too -- giving Naples that sense of being a place you start, not where you end.
