Uppsala Castle (Uppsala Slott)

Uppsala Castle was built during the time Sweden was on its way to become a great power in Europe. Kings Erik XIV, John III and Charles IX all remodeled and expanded the citadel into a representative renaissance palace. During Erik XIV's reign, the castle was the site of the Sture Murders. In 1630, King Gustavus II Adolphus announced the decision that Sweden should participate in the Thirty Years' War. It was in the castle that the Swedish government announced the abdication of Queen Kristina in 1654.
