Gothenburg, Göteborg in Swedish, is Sweden's second city and its window to the west. King Gustav II Adolf founded it in 1621 at the mouth of the Göta river, on the only stretch of coast where Sweden could reach the North Sea without passing Danish guns, and he hired Dutch engineers to build it: they drained the marsh, dug canals and laid out a star-shaped fortress town like the ones they knew at home. In the 1700s the Swedish East India Company made it rich on tea and porcelain from China, and in the 1900s it became an industrial city of shipyards, ball bearings and Volvo cars.
It's a more relaxed city than Stockholm, and Gothenburgers are famous for their puns, göteborgsvitsar: the new public sauna by the river was nicknamed Svettekôrka, the sweat church, after the fish market called the fish church. They they queue patiently for a giant cinnamon bun, and on a sunny day they're on a ferry to the islands before you've finished breakfast. The sea is everywhere: the shrimp, lobster and oysters of the west coast are the best in Sweden, and the car-free islands of the southern archipelago are an hour or so away on an ordinary tram and ferry ticket.
This plan starts on a Tuesday. Day one is the old canal city, the fish church and Haga, day two Avenyn, the art museum and Volvo, day three the river, Karlatornet and the old harbor district of Majorna, day four a day in the southern archipelago, and day five the parks of Slottsskogen and an evening at Liseberg.
