Uppsala was once the country's political, academic and spiritual center. The biggest attraction of the city is the Gothic cathedral, which is the place of coronation and rest of the Swedish kings. The temple is buried, among others Queen of Sweden Katarzyna Jagiellonka, wife of King Jan III Vasa of Sweden. Above her tombstone is the coat of arms of the Republic of Poland, and on the wall above a fresco depicting Krakow. There are also two huge bells in the cathedral, looted by the Swedes in Poland during the Northern War.
