Located on the northern bank of the Douro River, not far from the Atlantic Ocean, Porto is a city in Portugal, capital of the district of the same name and the second most populous city in the country. Porto is one of the most industrialized districts of Portugal, for this reason it is sometimes called A capital do norte (“The capital of the north”). From this derives the name of Portugal itself and the famous wine (Vinho do Porto). In 2001 Porto shared the recognition of European Capital of Culture with the Dutch city of Rotterdam. As part of these events, construction began on the large concert hall of the Casa da Música. In recent years, UNESCO has recognised the historic centre of Porto, the Ribeira district, as a world heritage site.
