Today Liege is a major educational hub, with a university and many high schools. It is a crossing point in Europe, Liège has the second biggest inner harbour and the 8th biggest cargo airport in Europe (Liège Airport). The city, that had a lot of problems since the 1970s because of the end of the steel industry and coal-mining, is now having a good economy thanks to the logistics and high tech industry (biotechnology, space industry, IT).
