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.
Heidelberg Castle
Heidelberg was first mentioned in 1196 as "Heidelberch". In 1155 Conrad of Hohenstaufen was made the Count Palatine by his half-brother Frederick Barbarossa, and the region became known as the Electorate of the Palatinate. The claim that Conrad's main residence was on the Schlossberg (Castle Hill), known as the Jettenbühl, cannot be substantiated. The name "Jettenbühl" comes from the soothsayer Jetta, who was said to have lived there. She is also associated with Wolfsbrunnen (Wolf's Spring) and the Heidenloch (Heathens' Well). The first mention of a castle in Heidelberg (Latin: ""castrum in Heidelberg cum burgo ipsius castri"") is in 1214, when Louis I, Duke of Bavaria of the House of Wittelsbach received it from Hohenstaufen Emperor Friedrich II. The last mention of a single castle is in 1294. In another document from 1303, two castles are mentioned for the first time:All that is known about the founding of the lower castle is that it took place sometime between 1294 and 1303. The oldest documented references to Heidelberg Castle are found during the 1600s:All of these works are for the most part superficial and do not contain much information. In 1615, Merian's "Topographia Palatinatus Rheni" described Prince Elector Ludwig V as he ""started building a new castle one hundred and more years ago"". Most of the descriptions of the castle up until the 18th century are based on Merian's information. Under Ruprecht I, the court chapel was erected on the Jettenbühl.
