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.
Karl-Liebknecht-Straße
World War II and the subsequent reconstruction of East Berlin as the capital of the German Democratic Republic meant the end for several of Berlin's important and well-known buildings. The most prominent of course being the Stadtschloss (“city palace”). It was first built as a castle as early as 1443 under Frederick II, Elector of Brandenburg. It was largely rebuilt as a palace a hundred years later and became the family seat of the House of Hohenzollern, rulers of the Kingdom of Prussia and later of the German Empire. The building was demolished in 1950 on the order of the East German government. It was replaced by the Palast der Republik, which was demolished from 2006 until 2008, after the removal of asbestos.
