Gothenburg is the second-largest and a major city in Sweden, situated off the Göta älv river on the country's west coast. The City of Gothenburg was founded in 1621 by King Gustavus Adolphus of Sweden. An important seaport, it's famed for its Dutch-style canals and leafy boulevards like the Avenyn, the city's main thoroughfare, lined with many cafes and shops.
