Uppsala Castle is a grand pink Renaissance fortress standing on a ridge above the city, begun by King Gustav Vasa in the 16th century and the scene of dramatic events in Swedish history. A ticketed visit and guided tours reveal its state rooms, the hall where a queen abdicated, dungeons and art exhibitions, while the terrace offers sweeping views over the cathedral and city. Combining royal history, striking architecture and fine vistas, it is one of Uppsala’s most important historic sights and a commanding presence over the old town.
