Dating from 1270, the Grey Friars monastery is the second-oldest structure in Stockholm; it's been the burial place for Swedish kings for more than 400 years. The redbrick structure, distinguished by its delicate iron-fretwork spire, is rarely used for services: it's more like a museum now. The most famous figures interred within are King Gustavus Adolphus, hero of the Thirty Years' War, and the warrior King Karl XII, renowned for his daring invasion of Russia, who died in Norway in 1718. The most recent of the 17 Swedish kings to be put to rest here was Gustav V, in 1950. The different rulers' sarcophagi, usually embellished with their monograms, are visible in the small chapels dedicated to the various dynasties.
