Since 2011 Barcelona has been a leading smart city in Europe. Barcelona is a transport hub, with the Port of Barcelona being one of Europe's principal seaports and busiest European passenger port, an international airport, Barcelona–El Prat Airport, which handles over 40 million passengers per year, an extensive motorway network, and a high-speed rail line with a link to France and the rest of Europe.
Some older sources suggest that the city may have been named after the Carthaginian general Hamilcar Barca, who was supposed to have founded the city in the 3rd century BC, but there is no evidence that Barcelona was ever a Carthaginian settlement, or that its name in antiquity, Barcino, had any connection with the Barcid family of Hamilcar.
During the Middle Ages, the city was variously known as Barchinona, Barçalona, Barchelonaa, and Barchenona.
Internationally, Barcelona's name is wrongly abbreviated to 'Barça'. However, this name refers only to FC Barcelona, the football club. The common abbreviated form used by locals is Barna.
