The only known relic of St. Olav in modern time is the Arm Relic, given by King Oscar I of Sweden and Norway to St. Olav’s Catholic Cathedral in Oslo in 1862. The relic, which is a human calf bone and not an arm bone, had then been kept in the Danish National Museum in Copenhagen since the late 17th century. The relic may have come to Copenhagen among several St. Olav relics that King Christian II of Denmark-Norway had requested from Nidaros after his coronation in Oslo in the summer of 1514.
