Hohenzollern Castle
With over 350,000 visitors per year Hohenzollern castle is one of the most visited castles in Germany. The castle is privately owned by the House of Hohenzollern, with two-thirds belonging to the Brandenburg-Prussian branch, and the balance to the Swabian branch. Since 1952, the Princess Kira of Prussia Foundation has used the castle for an annual summer camp for children. Whenever Prince George and his family are staying at the castle, the Prussian flag flies over the castle.
Monbijou Palace
Around 1820 the so-called "Germanic-Slavic Antiquities" were removed from the royal curiosities cabinet ("Kunstkammer") and housed in Monbijou Palace as the Museum for National Antiquities ("Museum für Vaterländische Alterthümer"). As the collections regularly expanded with the addition of new categories (paintings, jewelry, porcelain), the German emperor Wilhelm I finally made the palace with its 42 rooms accessible to the public as the "Hohenzollern Museum" in 1877. It was considered to be on the one hand an educational institution of cultural history, and on the other hand a place for the Hohenzollern dynasty to celebrate its own history and significance.
