 In 1666, Johan Hadorph the seventh National Antiquarian, established the "Placat och Påbudh, Om Gamble Monumenter och Antiquiteter" ("Signs and Decrees, of Old Monuments and Antiquities"), Sweden's first draft for an Antiquities Act.Aside from laws of the Vatican City, it was the first antiquities regulation in Europe.The decree made it possible to protect ancient monuments and sites from treasure hunters and vandalism, such as people who wanted to use ancient tumuli as brick kilns.
