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.
Hohenzollern Castle
The palace itself, sitting upon the outline of the second castle, is an open-air museum arranged in a u-shape that ends with Protestant and Catholic chapels. Sitting on top of the old casemates are the three story Gothic Revival buildings of Friedrich August Stüler's design, decorated with towers and pinnacles. The four towers of the palace are aligned to the bastions, with the Emperor's Tower to the Fuchsloch bastion, Bishop's Tower to the Spitz bastion, Markgraf Tower to the Scharfeck bastion, and Michael's Tower to the garden bastion. Attached to the main residential building, the Count's Hall, is the final tower, the Watch Tower (), which functions both as a staircase to the library and as the flag pole whenever the Hohenzollern family is residing in the castle.
