The Royal Armoury (Swedish: Livrustkammaren) is a museum in the Royal Palace in Stockholm, Sweden. It contains many artifacts of Swedish military history and Swedish royalty. It is the oldest museum in Sweden, established in 1628 by King Gustavus Adolphus when he decided that his clothes from his campaign in Poland should be preserved for posterity.
A drinking horn, made from one horn of the last recorded live aurochs was taken as war booty from Jaktorów, Poland by the Swedish Army during the Swedish invasion of Poland (1655–1660), and can now be found in the museum.
