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.
Province of Hohenzollern
Hohenzollern was established in 1850 by merging Hohenzollern-Sigmaringen and Hohenzollern-Hechingen, formerly independent principalities ruled by the Catholic branch of the House of Hohenzollern, that ceded their sovereignty to the Kingdom of Prussia ruled by the Protestant Hohenzollern branch and used the same dynastic coat of arms. Hohenzollern enjoyed all the rights of a full-fledged province of Prussia, including representation in the Prussian parliament, but its military matters and some civil matters were governed by the Oberpräsident of Rhine Province. Hohenzollern was Prussia's smallest province until Berlin city was separated from Brandenburg in 1881, and the least-populous with the last census recording 74,151 inhabitants in 1939. The province's size meant it was administered as a single "Regierungsbezirk" (district) from Sigmaringen, the provincial capital, which was further subdivided into seven "Oberamtsbezirke", although only four of these remained by 1925, when they were merged and re-divided as two new "Kreise". Hohenzollern was an exclave of Prussia, surrounded by Baden and Württemburg, and was the southernmost province.
