This is where one of the highlights of the entire exhibition is on display, the Gräf & Stift automobile in which the Austrian heir to the throne, Archduke Ferdinand and his wife Sophie Chotek were murdered on 28 June 1914 in Sarajevo. The traces of both assassinations are still clearly discernible on the car. Equally visible are the traces on two other items accessible to visitors: the blood-stained uniform of the Archduke, and the chaise longue on which the heir to the throne subsequently died of his injuries. Also on display are the weapons with which the assassins waited in Sarajevo for their moment to come, including Browning M.1910/12 pistols and a Kragujevac-hand grenade. In addition to the exhibits, photographs and films of the events are also displayed on digital monitors in the Sarajevo hall. Hall VI – World War I and the end of the Habsburg monarchy (1914–1918) Between 2012 and 2014, the group of halls dedicated to World War I was completely converted, modernised, and redesigned. To enlarge the initial exhibition area from 1,000 to 1,400 m2, the room height was reduced and an intermediate platform was introduced, so that the entire exhibition now spreads over three levels. As a result of these measures, some 2,000 items relating to World War I are now accessible to the public, about twice as many as were on display in the previous exhibition. A series of display cabinets contain the uniforms, weapons, and equipment of the warring powers. At the beginning of the exhibition, the themes focus on the mobilization of the troops in the summer of 1914, the Austrian infantry, followed by the cavalry. Next on display are uniforms and arms of the opposing parties, the Kingdom of Serbia, the Russian Empire, and the Kingdom of Italy, which declared war on Austria-Hungary in 1915. This led to the so-called Italian Front of 1915–1918, to which a separate area is dedicated to in the exhibition. A particular exhibit is the 7-cm M 1899 mountain gun which was positioned around the Ortler summit at an altitude of 3,850 meters, making it Europe's highest gun emplacement. Apart from the weapons, uniforms, and military equipment items, the exhibition also thematizes other related material in separate areas, such as women in war, the k.u.k. military justice system, escape and displacement, deprivation and propaganda, injury and emergency medical services, religion, war captivity, disability and death.
