of the city fell to the Hohenzollern. In 1567 under Christoph von Hohenzollern-Haigerloch the area around Haigerloch was an independent territory within the area of the Holy Roman Empire as Hohenzollern-Haigerloch. In this period, the present castle complex was built on the Schlossberg as the residence of the counts of Hohenzollern-Haigerloch, replacing the former high-medieval structure. In 1634 rule of the city descended to the line of Hohenzollern-Sigmaringen, whose residence city was the city of Haigerloch between 1737 and 1769. In the last months of World War II, Haigerloch was the location of the Kaiser Wilhelm Institute of Physics, part of the German nuclear programme, which had the goal of achieving practical use of nuclear fission. According to current view the atomic bomb was not a direct objective of this work, but initially only the construction of the Haigerloch Research Reactor (Forschungsreaktor Haigerloch), which was constructed in a beer cellar beneath the palace church. Through courageous negotiations by the pastor to rescue the reactor facility it was spared from demolition by an American command on April 24, 1945, and today is the site of the with a replica of the reactor.
