Ninth Fort  The Ninth Fort () is a stronghold in the northern part of Šilainiai elderate, Kaunas, Lithuania. It is a part of the Kaunas Fortress, which was constructed in the late 19th century. During the occupation of Kaunas and the rest of Lithuania by the Soviet Union, the fort was used as a prison and way-station for prisoners being transported to labour camps. After the occupation of Lithuania by Nazi Germany, the fort was used as a place of execution for Jews, captured Soviets, and others. At the end of the 19th century the city of Kaunas was fortified and by 1890 was encircled by eight forts and nine gun batteries. Construction of the Ninth Fort (its numerical designation having become its name) began in 1902 and was completed on the eve of World War I. From 1924 on, the Ninth Fort was used as the Kaunas City prison. During the years of Soviet occupation, 1940–1941, the Ninth Fort was used by the NKVD to house political prisoners pending transfer to Gulag forced labor camps. During the years of Nazi occupation, the Ninth Fort was put to use as a place of mass murder. 45,000 to 50,000 Jews, most from Kaunas and largely taken from the Kovno Ghetto, were transported to the Ninth Fort and killed by Nazis and Lithuanian collaborators in what became known as the Kaunas massacre. Notable among the victims was Rabbi Elchonon Wasserman of Baranovitch. In addition, Jews from as far as France, Austria and Germany were brought to Kaunas during the course of Nazi occupation and executed in the Ninth Fort. In 1943, the Germans operated special Jewish squads to dig mass graves and burn the remaining corpses. One squad of 62 people managed to escape the fortress on the eve of 1944. That year, as the Soviets moved in, the Germans liquidated the ghetto and what had by then come to be known as the "Fort of Death". The prisoners were dispersed to other camps. After World War II, the Soviets again used the Ninth Fort as a prison for several years. From 1948 to 1958, farm organizations were managed from the Ninth Fort. In 1958, a museum was established in the Ninth Fort. In 1959, an exhibition was prepared in four cells, telling of the Nazi war crimes carried out in Lithuania. In 1960, the discovery, cataloging, and forensic investigation of local mass murder sites began in an effort to gain knowledge regarding the scope of these crimes.
