Konopiště Castle (Czech pronunciation: [ˈkonopɪʃcɛ]; German: Schloss Konopischt) is a four-winged, three-storey castle located in Konopiště, now a part of the town of Benešov in Central Bohemian Region, Czech Republic. It has become famous as the last residence of Archduke Franz Ferdinand of Austria, heir to the Austro-Hungarian throne, whose assassination in Sarajevo triggered World War I. The bullet that killed him, fired by Gavrilo Princip, is now an exhibit at the castle's remote museum.
