Hohenzollern Castle (German: Burg Hohenzollern) is the ancestral seat of the imperial House of Hohenzollern. The third of three castles on the site, it is located atop Berg Hohenzollern, a 234 m (768 ft) bluff rising above the towns of Hechingen and Bisingen in the foothills of the Swabian Alps of central Baden-Württemberg, Germany.
A popular tourist destination, Hohenzollern castle has over 300,000 visitors per year, making it one of the most visited castles in Germany.
It is still privately owned, with two-thirds belonging to the Brandenburg-Prussian family line (presently Georg Friedrich, Prince of Prussia), and the balance by the Swabian (Karl Friedrich, Prince of Hohenzollern). Since 1954, the Princess Kira of Prussia Foundation has used it to provide a summer camp for needy children from Berlin.
