Gothenburg is the second-largest city in Sweden and the fifth-largest in the Nordic countries, and part of Västra Götaland County. It is situated by Kattegat, on the west coast of Sweden, and has a population of approximately 570,000 in the city center and about 1 million inhabitants in the metropolitan area.
Gothenburg was founded as a heavily fortified, primarily Dutch, trading colony, by royal charter in 1621 by King Gustavus Adolphus. In addition to the generous privileges (e.g. tax relaxation) given to his Dutch allies from the then-ongoing Thirty Years' War, the king also attracted significant numbers of his German and Scottish allies to populate his only town on the western coast. At a key strategic location at the mouth of the Göta älv, where Scandinavia's largest drainage basin enters the sea, the Port of Gothenburg is now the largest port in the Nordic countries.
