Hohenzollern Castle
The current castle was built by Hohenzollern scion Crown-Prince Frederick William IV of Prussia. Traveling through southern Germany en route to Italy in 1819 he wished to learn about his family's roots, so climbed to the top of Mount Hohenzollern. He would write in 1844 as King:
He engaged Friedrich August Stüler, who had been appointed Architect of the King for the rebuilding of Stolzenfels Castle in 1842 while still a student and heir of Karl Friedrich Schinkel, to design a new castle. Stüler began work on an ornate design influenced by English Gothic Revival architecture and the Châteaux of the Loire Valley in 1846. The impressive entryway is the work of the Engineer-Officer Moritz Karl Ernst von Prittwitz, considered the leading fortifications engineer in Prussia. The sculptures around and inside the castle are the work of Gustav Willgohs. Like Neuschwanstein Castle in Bavaria, Hohenzollern Castle is a monument to German Romanticism which incorporated an idealized vision of a medieval knight's castle. Lacking some of the fantastic elements and excesses of Neuschwanstein, the castle's construction served to enhance the reputation of the Prussian Royal Family.
Project Riese
Książ Castle (German: Fürstenstein) is located in the city of Wałbrzych (German: Waldenburg) . Its last owner in the inter-war period was the Hochberg family, one of the wealthiest and most influential European dynasties, Hans Heinrich XV, Prince of Pless and his English wife, Mary-Theresa Olivia Cornwallis-West (Princess Daisy). As a result of their extravagant lifestyle and the global economic crisis they fell into debt. In 1941, the castle and the lands were seized by the Nazi government, partly to pay taxes, partly as punishment for the perceived treason of their sons. At that time one of them served in the British Army, another in the Polish Armed Forces in the West. The castle, under the leadership of architect Hermann Giesler, was first adapted to accommodate the management of the state-owned railways (Deutsche Reichsbahn) but in 1944 it became part of Project Riese. In 1941–1944, it was also a place where parts of the collection of the Prussian State Library had been hidden.
