Калемегдан
In order to tie himself to his grandfather's legacy, Peter commissioned a bronze crown cast from a piece of Karađorđe's first cannon. In addition, the Order of Karađorđe's Star was introduced as Serbia's highest state decoration. The first feature-length film to emerge from Serbia and the Balkans, whose plot revolves around Karađorđe and his actions before, during and after the First Serbian Uprising, was released in 1911. Work soon began on the construction of the Church of Saint George, a Karađorđević dynasty mausoleum at Oplenac, near Topola. In 1913, a monument to Karađorđe was unveiled at Kalemegdan Park. During the Austro-Hungarian occupation of Serbia, the monument was torn down by the Austro-Hungarian Army and destroyed.
